Hit goal set for giant (7)
I believe the answer is:
goliath
'for giant' is the definition.
(synonyms)
'hit goal set' is the wordplay.
'set' is an anagram indicator (instruction to set the letters).
'hit'+'goal'='hitgoal'
'hitgoal' anagrammed gives 'GOLIATH'.
(Other definitions for goliath that I've seen before include "Giant Philistine laid low by David" , "Giant Philistine felled by David" , "I got Hal a giant form the bible" , "Biblical giant" , "Unusually large person" .)
