Jewish language (7)
I believe the answer is:
yiddish
'jewish language' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for yiddish that I've seen before include "German dialect widely used by European Jews before the Holocaust" , "Mixed language used by Jews of central and eastern Europe" , "I did shy away from Jewish language" , "Vernacular Jewish language" , "Old Jewish language" .)
