Language coming from overseas (4)
I believe the answer is:
erse
'language' is the definition.
(Erse is an example)
'coming from overseas' is the wordplay.
'coming from' indicates the answer is hidden within the clue.
'ERSE' is hidden within 'overseas'.
(Other definitions for erse that I've seen before include "Old language spoken by strange seer" , "Name sometimes given to languages of the Celts in Ireland and Scotland" , "Old name for Celtic languages" , "Old Gaelic for the seer" , "Old Scots or Irish Gaelic" .)
