Sense: adjective/1
Celtic is the broadest term, covering two main branches: Goidelic (Irish, Scots Gaelic, Manx) and Brythonic (Welsh, Breton, Cornish). Gaelic specifically refers only to the Goidelic branch — people often say 'Gaelic music' when they mean Irish or Scottish traditional music, but this is narrower than Celtic. Brythonic is a technical term for the British branch of Celtic languages (Welsh, Breton, Cornish) and is rarely used outside linguistics. Gaulish refers to the extinct Celtic language once spoken in ancient Gaul (modern France) before Latin replaced it. So if you are describing a shared tradition across Ireland, Scotland, Wales, and Brittany, use Celtic. If you are talking only about Irish or Scottish heritage, Gaelic may fit better, but remember it leaves out the Welsh and Breton connections.

Etymology
The word comes from Latin 'Celtae' (plural), which was borrowed from Greek 'Keltoi' — the name ancient Greek writers used for the peoples living in central and western Europe. The word entered English through French in the 1600s, with the modern spelling and pronunciation established by the 18th century. The 'c' is pronounced as a /k/ sound in standard English, though some people use an /s/ sound for certain contexts like the Boston Celtics basketball team.
