No time for abrupt language (4)
I believe the answer is:
erse
'language' is the definition.
(Erse is an example)
'no time for abrupt' is the wordplay.
'no' is a deletion indicator.
'time for' becomes 't' (I've seen this in other clues).
'abrupt' becomes 'terse' (I've seen this before).
'terse' with 't' taken out is 'ERSE'.
(Other definitions for erse that I've seen before include "Old Gaelic for the seer" , "Irish Gaelic language" , "Possibly the language" , "Kind of Gaelic for seer" , "Name sometimes given to languages of the Celts in Ireland and Scotland" .)
