Drive from south Sussex resort (5)
I believe the answer is:
shove
'drive' is the definition.
(thesaurus)
'south sussex resort' is the wordplay.
'south' becomes 's' ('S' can be a synonym of 'south').
'sussex resort' becomes 'hove' (I've seen this before).
's'+'hove'='SHOVE'
'from' acts as a link.
(Other definitions for shove that I've seen before include "Push in a rude manner" , "- - -halfpenny (pub game)" , "Push roughly" , "Push rudely" , "Barge" .)
