Gaelic
From UniLang Wiki
Gaelic, also called Scots Gaelic, is a Celtic language that is closely related to Irish and Manx, and is also related to Welsh and Breton. It is in no way related to (other than being an Indo-European language) Scots.
While Irish and Gaelic are closely related, there are some major differences between them, including their phonologies and morphologies, although their syntax systems are similar.
