Celtic Languages, subfamily of the Indo-European family
of languages. Geographically and historically, this subfamily is
divided into a Continental group (now extinct) and an Insular group.
On linguistic grounds the Insular languages fall into two groups:
the Brythonic (or British), including Breton, Cornish, and Welsh;
and the Goidelic (or Gaelic), including Irish, Scottish Gaelic (or
Erse), and Manx.
