Question: is welsh gaelic or celtic?
Answer: Cornish, Scottish Gaelic, Irish, Manx and Welsh belong to the Celtic branch of Indo-European. Celtic, in turn, divides into two distinct subgroups: P-Celtic (or Brythonic) and Q-Celtic (or Goidelic). Cornish and Welsh are P-Celtic languages, whilst Scottish Gaelic, Irish and Manx are Q-Celtic languages.
