Letter rules
Gaelic spelling looks unpredictable at first, but it is far more regular than English. A handful of rules explain almost every word — and once you know them, you can read a word aloud you have never seen before.
Slender with slender, broad with broad
Caol ri caol, leathann ri leathann
This is the rule that shapes Gaelic spelling more than any other. A consonant, or a group of consonants, must have vowels of the same kind on either side of it: slender (e, i) on both sides, or broad (a, o, u) on both sides.
It exists because a consonant sounds different next to a slender vowel than next to a broad one, and the vowels on either side are there to agree about which sound is meant. That is why so many Gaelic words seem to have spare vowels — some of them are not pronounced at all, and are only there to mark the consonant beside them.
You see the rule at work whenever an ending is added. The same plural ending is written -an after a broad vowel and -ean after a slender one:
| Word | Plural | Why |
|---|---|---|
| bròg (shoe) | brògan | The last vowel, ò, is broad, so the ending starts with broad a. |
| sgoil (school) | sgoilean | The last vowel, i, is slender, so an e is added to keep the l slender. |
- bròganBRAW-kunshoes
- sgoileanSKOL-unschools
- balaichBAL-eekhboysFrom balach, boy. Slendering the last consonant — writing an i before it — is a common way to make a plural.
- caitKATCHcatsFrom cat. The i turns the t slender, which changes its sound.
A handful of words break the rule — esan (him, emphatic) is one — and compound words often break it where the two parts meet.
The accent makes a vowel long
Stràc
Only vowels can take an accent, and modern Gaelic uses just one kind: the grave accent, which slopes down to the right (à, è, ì, ò, ù). It tells you the vowel is long.
Older books also use an acute accent on é and ó. The Gaelic Orthographic Conventions, the spelling standard used in schools and publishing, replaced these with the grave accent.
The accent is not decoration. Leaving it off can give you a different word, and it is required in exams.

Adding an h: lenition
Sèimheachadh
Grammar often softens the first consonant of a word, and in writing this is shown by putting an h after it. It happens after words like mo (my), glè (very) and the feminine article, and in the past tense of verbs — the grammar page lists the triggers.
Only nine letters can take the h: b, c, d, f, g, m, p, s and t. Vowels never do, and neither do l, n and r (their sound can soften, but the spelling stays the same). An s followed by g, m, p or t is also left alone, so sgoil stays sgoil.
| Letter | With h | Sounds like |
|---|---|---|
| b | bh | v |
| c | ch | the ch in Scots loch |
| d | dh | a throaty gh, or y beside e and i |
| f | fh | usually silent |
| g | gh | a throaty gh, or y beside e and i |
| m | mh | v, often nasal |
| p | ph | f |
| s | sh | h |
| t | th | h |

Hyphenated t- and h-
Ro-leasachain
Sometimes a t- or h- is joined to the front of a word with a hyphen. It is not part of the word itself — grammar adds it, usually to stop two vowels running into each other — and it is pronounced as if it were.
t- comes after the article an: before a masculine word starting with a vowel, and before a feminine word starting with s followed by a vowel, l, n or r. h- comes before a vowel after words like na (the, plural), a (her) and le (with).
The prefix is always lower case, even when the word after it has a capital.

Apostrophes mark a dropped letter
Asgair
As in English, an apostrophe shows where a letter has been left out. You will meet it in a few very common places:
- mo (my) and do (your) lose their vowel before a vowel or fh: m' athair, d' ainm.
- The feminine article an becomes a' before a softened consonant: a' chaileag.
- dh' goes in front of past-tense verbs that start with a vowel or fh: dh'òl, dh'fhàg.
- agus (and) and is are often shortened to 's.

Capital letters
Litrichean mòra
Names of people and places, languages, and days of the week start with a capital, much as in English. When a name has a lenited first letter or a hyphenated prefix, the capital goes on the name itself, not on the h or the prefix.
