Here's a breakdown:
* Gael: A member of a group of Celtic people who historically inhabited Ireland, Scotland, and the Isle of Man.
* Gaelic: This term refers to:
* The languages spoken by the Gaels, including Irish Gaelic, Scottish Gaelic, and Manx.
* The cultures and traditions of the Gaels, which are often associated with these languages.
"Gaellic" is still sometimes used, but "Gaelic" is the more widely accepted and accurate term.
