Curt, of few words (5)
I believe the answer is:
terse
I believe this clue is a double definition.
'curt' is the first definition.
(I know that curt can be written as terse)
'of few words' is the second definition.
(I've seen this in another clue)
(Other definitions for terse that I've seen before include "Pithy and concise" , "Curtly brief" , "Sparing with words; abrupt" , "Curt, laconic of speech" , "Curt among trees" .)
