In Battersea but not for long (5)
I believe the answer is:
terse
'for long' is the definition.
I can't judge whether this definition defines the answer.
'in battersea but' is the wordplay.
'in' indicates the answer is hidden within the clue.
'TERSE' is hidden within 'battersea but'.
'not' acts as a link.
Can you help me to learn more?
(Other definitions for terse that I've seen before include "Sparing with words; abrupt" , "Using few words" , "Brief; abrupt" , "Short and succinct" , "Succinct about trees" .)
