Spring, time for dispute (4)
I believe the answer is:
spat
'dispute' is the definition.
(spat is a kind of dispute)
'spring time' is the wordplay.
'spring' becomes 'spa' (spa can mean a mineral spring).
'time' becomes 't' (abbreviation).
'spa'+'t'='SPAT'
'for' is the link.
(Other definitions for spat that I've seen before include "Showed contempt" , "Minor conflict" , "Petty quarrel - gaiter" , "Old-fashioned legwear" , "Old leg wear - brief quarrel" .)
