Cast having fish after starter of figs (5)
I believe the answer is:
fling
'cast' is the definition.
(thesaurus)
'fish after starter of figs' is the wordplay.
'fish' becomes 'ling' (ling is a kind of fish**).
'after' says to put letters next to each other.
'starter of' indicates taking the first letters.
The initial letter of 'figs' is 'f'.
'ling' put after 'f' is 'FLING'.
'having' is the link.
(Other definitions for fling that I've seen before include "Throw, cast" , "Brief relationship" , "knees-up at 8 [HIGHLAND GAMES]" , "Vigorous Scottish dance" , "Highland dance - spell of way-out behaviour" .)
