In Battersea but not for long (5)
I believe the answer is:
terse
'for long' is the definition.
I can't tell whether this defines the answer.
'in battersea but' is the wordplay.
'in' indicates the answer is hidden within the clue.
'TERSE' is hidden in the letters of 'battersea but'.
'not' is the 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" .)
