Far from prolix (5)
I believe the answer is:
terse
'far from prolix' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for terse that I've seen before include "Succinct about trees" , "Curt - abrupt" , "Of speech, short and pithy" , "Brief and to the point" , "precise" .)
