Snappy contribution to better service (5)
I believe the answer is:
terse
'snappy' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'contribution to better service' is the wordplay.
'contribution to' says the answer is hidden in the clue.
'TERSE' is hidden in the letters of 'better service'.
Can you help me to learn more?
(Other definitions for terse that I've seen before include "Short, abrupt" , "Using few words" , "Of speech, short and pithy" , "Brief; abrupt" , "Brief and to the point" .)
