Goidelic languages
The term is used by linguists both for the historical processes which give rise to a change of pronunciation, and for their legacy, the processes which occur when words or morphemes of the appropriate form are brought together in continuous speech or writing. In the earlier history of the Goidelic languages, some changes of pronunciation comparable to those in British Celtic occurred, and the term is also used to label them, but those processes have no counterparts in the grammars of the surviving modern Goidelic languages, Irish and Scottish Gaelic.
