Concise, short (5)
I believe the answer is:
brief
I believe this is a double definition.
'concise' is the first definition.
(similar in meaning)
'short' is the second definition.
(similar in meaning)
(Other definitions for brief that I've seen before include "Brusque - lawyer (slang)" , "put in the picture" , "Prime" , "Short or concise" , "Fibre (anag.)" .)
