# Gàidhlig 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.
