Crisp, brief (5)
I believe the answer is:
terse
I believe this is a double definition.
'crisp' is the first definition.
(I know that crisp can be written as terse)
'brief' is the second definition.

(Other definitions for terse that I've seen before include "Of speech, short and pithy" , "Crisply brief" , "Brusque among trees" , "Sententious" , "precise" .)
