End spoken language (6)
I believe the answer is:
finish
'end' is the definition.
(I know that end can be written as finish)
'spoken language' is the wordplay.
'spoken' shows a homophone (sound like).
'language' becomes 'Finnish' (language of Finland).
'finnish' is a homophone of 'FINISH'.
(Other definitions for finish that I've seen before include "Perfect" , "train socially" , "Cease, conclude" , "Complete or terminate" , "Pefect" .)
