Welsh (United Kingdom) style guide

Voice

  • Clear, friendly, concise. Everyday conversational language, not formal or technical register.
  • Not teenagers only. No technical jargon. No overly colloquial language. Keep it simple enough for the average user.
  • Write short, easy-to-read sentences. One idea per sentence.
  • Avoid passive voice. Use active, direct sentences.
  • Technical terms for technical audiences, common words for consumers.
  • Translate the intended meaning, not word by word. Non-standard word choices OK if they keep the source intent.
  • Avoid slang. Be conversational but professional.
  • Address the user as you. No third-person user.
  • No corporate we. Keep the focus on you.
  • Use the polite 2nd person (-wch forms) to address the user.
  • For unambiguous commands use the personal imperative. Where ambiguous, or where space is tight, use the verb noun form.
  • You are now connected to the Internet. -> Rydych nawr wedi'ch cysylltu â'r Rhyngrwyd, not Rwyt ti nawr wedi dy gysylltu â'r Rhyngrwyd

  • Are you sure you want to exit Setup? -> Ydych chi'n siŵr eich bod am adael y broses gosod?, not Wyt ti'n siŵr dy fod am adael y broses gosod?

  • The message has been sent -> Anfonwyd y neges, not Mae'r neges wedi'i hanfon
  • The message is being sent -> Mae'r neges wrthi'n cael ei hanfon, not Anfonir y neges
  • No single word translates Yes and No in every context. The answer must match the question.
  • Where possible use Iawn (OK) instead of the various translations of Yes. In the negative the short form Na is usually acceptable.
  • Yes -> Iawn; OK -> Iawn; No -> Na
  • Exception: when asked if you are sure you wish to do something, use Ydw.
  • Active, not passive: Mae'r cyfrifiadur yn cau., not Cafodd y cyfrifiadur ei gau.
  • Active, not passive: Cadwodd y rhaglen y ffeil, not Cafodd y rhaglen ei chadw gan y ffeil.
  • For AI prompt instructions use the formal form of address (chi) and the -wch imperative.

Word choice

  • Use terminology consistently. Use existing translations from the reference materials and approved terminology for key terms, technical terms, product names.
  • Prefer short, simple, everyday words. They save screen space and read faster.
  • application, program -> app
  • pick for fun, less formal, light-weight situations (pick a color, not choose a color); choose for formal situations. Do not use select unless the UI requires it.
  • drive for any drive type. Use the specific drive type only when needed.
  • get only as a synonym for obtain or come into possession of.
  • info in most situations, and when pointing the reader elsewhere (for more info, see <link>). Use information only where it fits better.

  • Dyn/Menyw -> Person/Pobl
  • Bachgen/Merch -> Plentyn/Plant
  • For generalizations use plural noun forms (pobl, unigolion, myfyrwyr).
  • No gendered pronouns (ei, hi, e) in generic references. Instead: rewrite in the second or third person (chi/ti or un); rewrite with a plural noun and pronoun; use an article instead of a pronoun (y ddogfen, not ei ddogfen); refer to the person's role (darllenydd, gweithiwr, cwsmer, cleient); use person or unigolyn.

  • Avoid sentences referring to a single person of unknown gender. Make the subject plural.
  • Never use he or she, him or her, his or hers. Avoid a slash to combine genders. Exception: in License Terms or column and row headers, ef/hi is allowed.

Accessibility

  • normal person; healthy person -> person without a disability; person arferol; person iach -> person heb anabledd
  • Use generic verbs that apply to all input methods and devices.
  • Click -> Select; Clicio -> Dewis
  • Keep paragraphs short and sentence structure simple. Aim for one verb per sentence. Read text aloud and imagine a screen reader.

  • Accessibility options and programs serve people with cognitive, hearing, physical, or visual disabilities. Some accessible products and services may not be available in Welsh-speaking markets.

Abbreviations

  • Abbreviate only where the UI lacks space, mainly button or option names.
  • Use the full Welsh translation whenever possible.
  • No periods in abbreviations. Extended characters are not used in abbreviated form.
  • er enghraifft: ee, not e.e.
  • hynny yw: hy, not h.y.
  • ac yn y blaen: ayb, not a.y.b.
  • dalier sylw: ds, not d.s.
  • ôl nodyn: on, not o.n. or ôn
  • Use a non-breaking space (CTRL+SHIFT+SPACEBAR) in any abbreviation.
  • Where non-breaking spaces cannot be used (Help files), write the abbreviation without a space so one letter does not move to the next line.
  • Use the full term in Welsh for measurements where possible; it reads more clearly.
  • Gigabyte: GB -> GB
  • Gigabit: GBit -> GDid
  • Kilobyte: KB -> KB
  • Kilobit: KBit -> KDid
  • Megabyte: MB -> MB
  • Megabit: MBit -> MDid

  • Terabit: TBit -> TDid
  • Bits per second: Bit/s -> Did/e

  • Use the same type for similar measurements, e.g. frames per second -> F/s
  • No plural form for measurement abbreviations.
  • " is acceptable in packaging and tables, not in body text.
  • Do not abbreviate any other words in Welsh.

Acronyms

  • Acronyms are made of the initial letters of the major parts of a compound term, e.g. WYSIWYG (What You See Is What You Get), DNS (Domain Name Server), HTML (Hypertext Markup Language).
  • Do not add a generic term after an acronym when one letter of the acronym already stands for it. Correct this even when the English source does it.
  • Redundant: Galwad RPC, Iaith HTML, Protocol TCP/IP, Rhif PIN
  • Only two acronyms are localized in Welsh: UK -> DU, USA -> UDA
  • All other acronyms stay in English and are not spelled out: ANSI -> ANSI, ISO -> ISO, ISDN -> ISDN

Adjectives

  • Many Welsh adjectives have a masculine form (bachgen cryf), a feminine form (merch gref) and a plural form (ceffylau cryfion). Use the plural and feminine forms only if the form is very familiar.
  • A soft mutation occurs in an adjective after a singular feminine noun.
  • Control Panel -> Panel Rheoli, not Panel Reolaethol
  • Recovery System -> System Adfer, not System Adferol
  • Possessive adjectives: see Pronouns.

Articles

  • Three forms of the article exist in Welsh: yr, y, 'r. Use them to make a noun specific.
  • Change the visual effects and the sounds on the PC -> Newid effeithiau gweledol a'r synau ar y cyfrifiadur
  • In phrases with this, where the object is obvious, the Welsh translation of this may be omitted. Use the determiner if omission creates ambiguity.
  • Delete this file -> Dileu'r ffeil, not Dileu'r ffeil hon
  • Non-translated feature names take no definite or indefinite article, as in English, and stay unchanged.
  • Translated feature names are not preceded by articles: Calculator -> Cyfrifannell, Paint -> Paent
  • For an English loan word, check: motivation (does the word have features allowing integration into the Welsh noun class system?), analogy (is there an equivalent Welsh term whose article could be used?), frequency (which article is most used in other technical documentation?).
  • Always check approved terminology to confirm a new loan word and its article.
  • Enter a valid URL. -> Rhowch URL dilys.

Capitalization

  • Follow English practice for capitalization, but do not mimic the source. English source strings capitalize far more nouns and verbs than Welsh needs. Over-capitalization is awkward and creates UI inconsistency.
  • If a capitalized English noun becomes two Welsh words, be consistent: capitalize both, neither, or one, and apply the rule consistently.
  • Electronic terminology is not usually capitalized in Welsh.
  • E-mail -> e-bost; E-mail (verb) -> e-bostio; Website -> gwefan; web -> y we
  • Exceptions: y Rhyngrwyd and y We Fyd-eang.
  • English headings capitalize all nouns, pronouns, adjectives, verbs, adverbs and subordinate conjunctions (that, until, which). Do not do this in Welsh headings. Follow normal Welsh capitalization rules. The same applies to software strings.
  • Switching between Windows -> Newid rhwng Windows, not Newid Rhwng Windows

Compounds

  • Compounds must be understandable and clear. Avoid overly long or complex compounds; express the relationship between components verbally instead. Unintuitive compounds are an intelligibility and usability problem.
  • Nouns, adjectives, pronouns, verb-nouns and prepositions may compound into single words. No length restriction. The second part of the compound mutates.
  • Hibernate -> Trwmgysgu; Invert -> Gwrthdroi; Metadata -> Metaddata; Shuffle -> Hapdrefnu; AutoCorrect -> Awtogywiro
  • A hyphen is generally needed when the second element is a one-syllable word. It is usually not needed when the second element has more than one syllable.
  • Di-waith -> Diweithdra; Cyd-fynd -> Cydadolygiad; Gor-ddweud -> gorweithio
  • Exceptions: ad- + words beginning with t -> ad-drefnu; cyd- (fellow/joint) -> cyd-bwyllgor
  • Use a hyphen after ail-, arch-, blaen-, cam-, lled-, ôl-, pen-, prif-, and after uwch- and is- when they refer to an organisation or a job.
  • Exceptions: Prifysgol, Prifddinas (one word); Prif meaning chief -> Prif Weinydd (two words).
  • A hyphen always follows the prefix e-: e-bost, e-bostio, e-lywodraeth
  • Internet Accounts -> Cyfrifon Rhyngrwyd; Logon script processing -> Prosesu sgript Mewngofnodi; Internet News Server Name -> Enw Gweinydd Newyddion Rhyngrwyd
  • Add to a product or component name with a hyphen, or build a periphrastic construction where a hyphen is wrong. In Welsh the component name comes before the product name.
  • Windows password -> Cyfrinair Windows
  • Microsoft Word document -> Dogfen Microsoft Word
  • Microsoft SQL Server database -> Cronfa Ddata Microsoft SQL Server
  • Microsoft Dynamics 365 product family -> Teulu cynnyrch Microsoft Dynamics 365
  • Compounds with an abbreviation or numeral followed by a component name: translate the component, keep abbreviations in English.
  • USB drive -> gyriant USB; 2-D gridlines -> llinellau grid 2-D; 24 bit color value -> gwerth lliw 24 did
  • For a plural abbreviation use the ending -s, not -au.
  • URLs -> URLs, not URLau; USBs -> USBs, not USBau

Contractions

  • English voice uses contractions wherever possible to sound conversational: Do not -> Don't
  • Where one word ends in a vowel and the next begins with a vowel, and it is grammatical, use an apostrophe to join both words and omit one vowel. Replace the definite article y with r after a vowel.
  • Color of: Lliw y -> Lliw'r
  • Has been: Wedi ei -> Wedi'i
  • File name: Enw y ffeil -> Enw'r ffeil

Conjunctions

  • Conjunctions convey a conversational tone. Starting a sentence with a conjunction is allowed.
  • yn yr un modd â -> fel
  • unwaith y byddwch chi wedi -> pan
  • oherwydd -> felly
  • o achos -> gan
  • os byddwch chi byth yn -> os
  • hyd oni byddwch yn -> nes
  • a chithau wedi -> ar ôl
  • Do not copy English heading capitalization of subordinate conjunctions into Welsh. Same for software strings.
  • Switching between Windows -> Newid rhwng Windows, not Newid Rhwng Windows

Genitive

  • Some Welsh noun phrases read as either adjectival or genitive. After a feminine noun an adjective takes a soft mutation; a genitive does not mutate: merch wen (adjectival) but merch Gwen (genitive).
  • Use the soft mutation only where the adjectival sense is unambiguous: neges rydd (adjectival) but neges rhybudd (genitive).
  • Action Center -> Canolfan Gweithredu
  • Do not attach a genitive s to a product name. It could read as a modification of the name.

Localizing colloquialism, idioms, and metaphors

  • Do not replace a source colloquialism with a Welsh colloquialism unless it is a perfect and natural fit for the context.
  • Translate the intended meaning, not the literal colloquialism, but only if the meaning is integral to the text.
  • If the colloquialism can be omitted without affecting the meaning, omit it.

Modifiers

  • Mutation changes the first letter of a word. It follows grammar rules and can break translations where the phrasing forces a mutation. Where possible, rephrase Welsh menu text to remove the need for a grammatical mutation in any following portion.
  • In bulleted lists mutate only the first bullet point, if needed. If letters or numbers are used, the letter or number counts as part of the text, so do not mutate the first bullet point.
  • Selecting this will enable you to either shut your computer down • allow the user to log off • -> Wrth ddewis hwn gallwch naill ai gau eich cyfrifiadur • caniatáu i'r defnyddiwr adael •
  • Selecting this will enable you to either a) shut your computer down b) allow the user to log off -> Wrth ddewis hwn gallwch naill ai a) cau eich cyfrifiadur b) caniatáu i'r defnyddiwr adael
  • Selecting this will enable you to either 1. shut your computer down 2. allow the user to log off -> Wrth ddewis hwn gallwch naill ai 1. cau eich cyfrifiadur 2. caniatáu i'r defnyddiwr adael
  • Check required mutations against Y Golygiadur, Llawlyfr i awduron a golygyddion.

Nouns

  • Welsh nouns are masculine, feminine, or plural. A singular form always follows a number.
  • Loan words follow the syntactic and morphological rules of Welsh.
  • Delete the format. -> Dileu'r fformat hwn.
  • Format this word. -> Fformatio'r gair hwn.
  • Invalid formats. -> Fformatau annilys.
  • Please format this file. -> Fformatiwch y ffeil hon.
  • Welsh nouns are feminine (llyfrgell) or masculine (llun). Plurals: llyfrgelloedd, lluniau.
  • this library -> y llyfrgell hon; this picture -> y llun hwn

  • English loanwords usually take -aid, -oedd, -au or -s in the plural.
  • Clients -> Cleientiaid; Blogs -> Blogiau; Engines -> Injans; Formats -> Fformatiau; Diagrams -> Diagramau

Prepositions

  • Use the correct preposition. Do not omit it or change the word order under English influence. Avoid anglicisms.
  • Starting or ending a sentence with a preposition is acceptable.
  • For to in the context of sending e-mail use at, not i, which denotes a place, not a person.
  • For to in the context of page numbers use i.
  • Use â/ag after peidio.

  • Any comments you have -> Unrhyw sylwadau a fydd gennych, not Unrhyw sylwadau y bydd gennych

Punctuation

  • Put a space after commas and periods. Only one space after a punctuation mark.
  • Follow open punctuation. Use as little unnecessary punctuation as possible.
  • No semicolon at the end of bullet points.
  • Do not punctuate the address in letters, nor the Annwyl (Dear)… greeting, nor Yn gywir (Yours sincerely)…
  • Bulleted lists: mutate only the first bullet point, if needed. With letters or numbers, do not mutate the first bullet point. See Modifiers.

  • Do not let a long line follow a colon (:–).
  • Three dash characters are used in Welsh.

  • Undo -> Dad-wneud
  • En dash: used as a minus sign, usually with spaces before and after. -3 -> -3
  • En dash also marks number ranges, such as page numbers. No spaces around it in that case.

  • Setup the program—you have downloaded—on the PC -> Gosodwch y rhaglen—y byddwch wedi'i llwytho i lawr—ar y cyfrifiadur.

  • Handle symbols and non-breaking spaces as the English source does.
  • Exception: never use the ampersand (&) in Welsh.

Verbs

  • blog -> blog, blogio, blogiwch
  • format -> fformat, fformatio, fformatiwch
  • Ancillary verbs common in English may be omitted in Welsh.
  • To make use of -> defnyddio, not gwneud defnydd o
  • To pay a visit -> ymweld â, not talu ymweliad â
  • To give consideration -> ystyried, not rhoi ystyriaeth i
  • To make a decision -> penderfynu, not gwneud penderfyniad
  • Translate verbs consistently in error messages. If it is grammatical to omit the predicate be, omit it, but stay consistent across all error messages. Be concise without changing the meaning.
  • The document is too large. / Document too large. -> Mae'r ddogfen yn rhy fawr. Stay consistent in your use of the verb to be.
  • Access was denied. / Access denied. -> Dim mynediad.
  • The file '%s' is an unknown graphics format. -> Mae'r ffeil '%s' yn fformat graffeg anhysbys. In complete sentences use verbs and the same tense as the source. Rephrase is with have if needed.
  • The application may attempt to convert the graphic. -> Gall y rhaglen geisio trosi'r graffigyn. may + Verb can be rephrased as Verb + possibly.
  • A problem occurred while trying to connect to the network share '%1!s!'. -> Problem wrth geisio cysylltu â'r rhan rhwydwaith '%!s!'. Shorten and rephrase, e.g. A problem occurred while connecting to the network share '%1!s!'
  • The following error occurred: '%1!s!' (error #%2!lx!) -> Dyma'r gwall: '%1!s!' (gwall #%2!lx!) Shorten where possible, e.g. Error: '%1!s!' (error #%2!lx!)
  • An unknown error has occurred./ No error occurred. -> Gwall anhysbys./ Dim gwall. Shorten where possible, e.g. Unknown error. / No error
  • Decide between gallu (able) and cael (allow) in error messages. Usually the message means the user is not allowed, not unable.
  • You cannot save this file. -> Chewch chi ddim cadw'r ffeil., not Allwch chi ddim cadw'r ffeil.
  • You can open this folder. -> Cewch agor y ffolder., not Gallwch agor y ffolder.
  • You will not be able to open this folder. -> Chewch chi ddim agor y ffolder., not Allwch chi ddim agor y ffolder.
  • The program saved (past) -> Cadwodd y rhaglen
  • The program has saved (perfect) -> Mae'r rhaglen wedi cadw
  • The program had saved (pluperfect) -> Roedd y rhaglen wedi cadw

Localization considerations

  • Adapt the translated text to local language, customs, and standards.
  • The text must read as composed in Welsh, with idiomatic syntax and terminology, and high terminological consistency.
  • Graphics need no change unless they contain text.
  • Use a non-breaking space (CTRL+SHIFT+SPACEBAR) in any abbreviation.
  • Where non-breaking spaces cannot be used (Help files), write the abbreviation without a space.

Applications, products, and features

  • Application and product names are rarely translated. Feature names are occasionally trademarked too, e.g. IntelliSense.
  • Version numbers always contain a period: Version 4.2 -> Fersiwn 4.2
  • Version numbers are usually part of version strings, but are not technically the same thing.

Error messages

  • Error messages tell the user of an error that must be corrected for the program to keep running. They can prompt an action or tell the user a reboot is needed.
  • Make target translations natural and empathetic, not robot-like.
  • Something went wrong -> Aeth rhywbeth o'i le
  • Not enough memory to process this command. -> Does dim digon o gof i broesu'r gorchymyn hwn
  • Use consistent terminology and language style. Do not just translate the US wording.
  • Error messages must not be patronizing. Help the user avoid the same error in future.
  • Cannot … -> Does dim modd…
  • Could not … -> Doedd dim modd…
  • Failed to … / Failure of … -> Wedi methu…
  • Cannot find … / Could not find … / Unable to find … / Unable to locate … -> Heb ganfod…
  • Not enough memory / Insufficient memory / There is not enough memory / There is not enough memory available -> Dim digon o gof ar gael
  • ... is not available / ... is unavailable -> Dim … ar gael
  • File not found. / File was not found. / The file was not found. -> Heb ganfod y ffeil.
  • Not enough memory. -> Dim digon o gof. Treat not enough as insufficient.
  • Wrong file type. -> Math anghywir o ffeil. Treat wrong as incorrect.
  • Invalid file type. -> Math annilys o ffeil. Treat invalid as illegal.
  • An illegal setting name has been entered. -> Mae enw'r gosodiad yn annilys.
  • %1 has a bad format. -> Mae fformat %1 yn annilys. Use invalid, not bad, unless the meaning is physically broken.
  • Object doesn't support current locale setting. -> All y gwrthrych ddim delio â'r gosodiad locale presennol.
  • Use one basic syntax for all negative sentences. Use standard word order; watch where the negative marker sits.
  • The negative word Nid/Ni may be omitted.
  • Object doesn't support current locale setting. -> All y gwrthrych ddim delio â'r gosodiad locale presennol., not Ni all y gwrthrych ddelio â'r gosodiad locale presennol.
  • You cannot copy the file. -> Chewch chi ddim copïo'r ffeil, not Ni chewch chi gopïo'r ffeil
  • Na is the negative of a (before a consonant). Nac is the negative of ac (before a vowel). Na is the negative of â (before a consonant). Nag is the negative of ag (before a vowel).
  • Find out what will replace a placeholder, so the sentence stays grammatical.
  • %d, %ld, %u, %lu mean <number>; %c means <letter>; %s means <string>.
  • "Checking Web %1!d! of %2!d!" means "Checking Web <number> of <number>."
  • "INI file "%1!-.200s!" section" means "INI file "<string>" section."
  • In English source strings placeholders sit where they naturally occur. Numeral placeholders typically precede the noun. The same is true in Welsh.
  • %d minutes -> %d munud
  • Nouns used with %lu placeholders take the singular form in Welsh, because a Welsh noun keeps its singular form directly after a number: 3 files -> 3 ffeil
  • %lu files -> %lu ffeil, not %lu ffeiliau
  • Where a placeholder may be replaced by items that differ in mutation, or force a different form (soft mutation of the noun after the number 2), the software cannot handle every option. Where you cannot rephrase to avoid an ungrammatical form, use phrases and idioms grammatical in most instances. The default common form in Welsh after a placeholder is the unmutated form.
  • %lu documents -> %lu dogfen, not %lu ddogfen
  • Where adjectives and nouns agree and the noun is a placeholder, know the exact string so a preceding adjective inflects correctly. Most source strings are already worded to avoid this.
  • Where the language has noun-verb agreement, reword the translation to avoid an ungrammatical sentence.
  • Find the gender of a term in the latest terminology. If the term is absent, use the gender listed first in Geiriadur Prifysgol Cymru.
  • Replace invalid %s? (Replace invalid data?, Replace invalid file?) -> Disodli %s annilys?
  • %s already exists (File already exists, Name already exists) -> Mae %s eisoes yn bodoli
  • %s is now set as your personal contact. (Regina is now set as your personal contact, Mr. Kim is now set as your personal contact) -> %s ydy eich cyswllt personol nawr.
  • %s stopped working and was closed (The application stopped working and was closed, The program stopped working and was closed) -> Mae %s wedi cau oherwydd nad oedd yn gweithio bellach.
  • Describe the action the user must take before the purpose of the action. The action always precedes the purpose in Welsh.
  • Avoid personified inanimate subjects. Replace active constructions with passive ones where possible. Rephrase and change the word order.
  • Setup encountered an error while creating your startup disk. -> Gwall gosod wrth greu'r ddisg cychwyn.
  • Setup cannot find the remote computer. -> All y broses gosod ddim dod o hyd i'r cyfrifiadur pell.
  • Setup cannot get disk information. -> All y broses gosod ddim cael gwybodaeth disg.
  • Remove any existing settings to free space. -> Tynnwch unrhyw osodiadau presennol i ryddhau lle.
  • Attempt to remove current directory -> Rhowch gynnig ar dynnu'r cyfeiriadur presennol Use a passive construction instead of Attempt to ....

Keys

  • In Welsh, key names such as arrow keys, function keys and numeric keys appear in normal text, not in small caps.

Keyboard shortcuts

  • Underlined or highlighted letters in menu options, commands or dialog boxes are keyboard shortcuts. Examples: New, Cancel, Options.
  • Slim characters (I, l, t, r, f) can be used as keyboard shortcuts: yes
  • Characters with downstrokes (g, j, y, p, q) can be used: yes
  • Extended characters can be used: yes, but avoid this.
  • An additional letter in brackets after the item name can be used: yes
  • A number in brackets after the item name can be used: yes
  • A punctuation sign in brackets after the item name can be used: yes
  • Duplicate keyboard shortcuts are allowed when no other character is available: yes
  • No keyboard shortcut is assigned when no more characters are available, minor options only: yes
  • If no more characters are available, assign the shortcut to an extended character. The user applies the normal keyboard character as the shortcut.
  • access key: a subtype of keyboard shortcut. A letter or number the user types to reach UI controls with text labels. Assigned to top-level controls so the user moves through the UI quickly with the keyboard. Example: F in Alt+F. In UI localization: H&ome. Most access keys are used with the Alt key.
  • key tip: the letter or number shown in the ribbon when Alt is pressed. In UI localization it is the last character after the ` character. Example: HomeH`
  • shortcut key: a subtype of keyboard shortcut. A key the user types to perform a common action without going through the UI. Not available for every command. Example: Ctrl+N, Ctrl+V. Most shortcut keys are used with the Ctrl key. Ctrl+letter combinations and function keys (F1 through F12) are usually the best choices.

English pronunciation

  • Pronounce unlocalized English terms and product names the English way.
  • If Welsh has an established pronunciation for a common term such as server, use the local pronunciation.
  • Adapt pronunciation to the Welsh phonetic system where the original sounds very awkward.
  • SecurID -> [sı'kjuər aı di:]
  • .NET -> [dot net]
  • Skype -> [skaɪp]
  • Product names are always pronounced as in the source language.
  • Some acronyms are pronounced like real words, adapted to local pronunciation: RADIUS, RAS, ISA, LAN, WAN, WAP, MAPI, POP
  • Other abbreviations are pronounced letter by letter: ICMP, IP, TCP/IP, XML, HTML, OWA, SQL, XP
  • Pronounce www as w driphlyg.
  • Omit the dot, or read it out. If read out, pronounce it the Welsh way, as dot.
  • http://www.microsoft.com/ -> w driphlyg dot Microsoft dot com blaen slaes
  • Most punctuation marks are implied by the sound of the voice, e.g. ? ! : ; ,
  • En dash (–) emphasizes an isolated element. Pronounce it as a comma, a short pause.
  • Pronounce special characters such as / \ ˘ < > + - using the approved Welsh terminology.

Tone

  • Match the tone to the target audience: informal, playful and inspiring for consumer products and games; formal, informative and factual for technical texts.
  • Aim for the register described in Gramadeg yr Iaith Gymraeg as cywair safonol rhyddfrydol (liberal standard). It sits between the formal conservative register and a colloquial informal register.
  • Avoid dialect-specific word forms.
  • Follow the 12 rules of Cymraeg Clir (Plain Welsh):
    1. Use simple, concise, everyday language.
    1. Address your readers directly.
    1. Use the natural words, phrases and structure of Welsh.
    1. Use short sentences, no more than 25 words.
    1. Keep to one sentence, one idea.
    1. Use active verbs: Dechreuodd y cyngor 50 o brosiectau, not Dechreuwyd 50 o brosiectau gan y cyngor
    1. Say clearly who is doing something: we, you, they.
    1. Use verbs rather than nouns.
    1. Use informal verbs and pronouns.
    1. Avoid official language full of jargon and technical terms. Explain any unfamiliar term.
    1. Divide long sentences into shorter points or bullet points.
    1. Use punctuation to help the reader.
  • Use these verb forms: Rydw i / Dydw i ddim, Mae ef / Dydy ef ddim, Mae hi / Dydy hi ddim, Rydych chi / Dydych chi ddim, Rydyn ni / Dydyn ni ddim, Maen nhw / Dydyn nhw ddim

  • Do you want to shut down? -> Ydych chi am gau lawr?, not Ydych am gau lawr?
  • The verb often mutates too: beth allech ei wneud, beth ddylech ei wneud
