Gaidhlig Language

Gàidhlig (Scottish Gaelic) is a Celtic language closely related to Irish, spoken mainly in the Scottish Highlands and Islands. It has official recognition in Scotland, is used in education, broadcasting (e.g. BBC ALBA), and public signage, though the number of fluent first-language speakers is relatively small.

Writing system

Gàidhlig uses the Latin alphabet with the grave accent (à, è, ì, ò, ù) marking long vowels — a different diacritic convention from Irish's acute accent (síneadh fada), despite the two languages' close historical relation. As in Irish, the accent is not decorative: it can distinguish otherwise identical-looking words, so it should never be dropped or normalized away.

Initial mutations

Gàidhlig lenites (softens) the initial consonant of a word depending on grammatical context, similar in kind to Irish's séimhiú and Welsh's soft mutation. Lenition is typically marked by inserting an "h" after the initial consonant, triggered after certain possessive pronouns, prepositions, and in constructions like the feminine noun after "the." Example: màthair (mother) becomes mhàthair after "mo" (my): mo mhàthair. As with the other Celtic mutation systems, a lenited word must still be recognized and looked up under its unmutated root form.

Word order

Gàidhlig uses verb-subject-object (VSO) word order, unlike English's subject-verb-object: the verb comes first in a standard declarative sentence. Translating from or into English requires reordering rather than a word-for-word substitution.

Vocative case

Gàidhlig retains a vocative case, used when addressing someone directly by name or title. Addressing a person often triggers lenition (and sometimes a case-specific ending) on their name: for example, "Iain" (John) becomes "a Iain" when calling to him directly. Getting the vocative form wrong is a distinctive, noticeable error when writing dialogue or direct address in Gàidhlig.

Gàidhlig vs. Gaeilge

Despite their historical closeness — both descend from Old Irish — and some shared vocabulary, Gàidhlig and Gaeilge (Irish) are distinct languages today, not dialects of one language. They differ in orthography (grave vs. acute accents), vocabulary, and grammar to the point of limited mutual intelligibility in writing, and text or translation requests for one should never be treated as interchangeable with the other. See Gaeilge Language for the Irish-specific conventions.

Regional variation

There is some regional variation in vocabulary and pronunciation across the Highlands and Islands (e.g. Lewis, Skye, and mainland dialects), but Gàidhlig's speaker base is small enough that a standardized written form (used in education and broadcasting) is generally the safe default for general-purpose text.

Common pitfalls

• Confusing Gàidhlig with Gaeilge (Irish) or treating them as interchangeable — they are related but distinct languages; see Gaeilge Language.
• Dropping the grave accent on long vowels, or substituting the acute accent from Irish by mistake.
• Applying no lenition, or lenition where an unmutated form is actually required.
• Getting the vocative case wrong when writing direct address (calling or speaking to someone by name).
• Defaulting to English SVO word order instead of Gàidhlig's VSO order.
