Almost the perfect place for a fling (5)
I believe the answer is:
heave
'a fling' is the definition.
(thesaurus)
'almost the perfect place' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'the perfect place' becomes 'heaven'.
'heaven' with its final letter taken off is 'HEAVE'.
'for' is the link.
(Other definitions for heave that I've seen before include "Lift or haul with great effort" , "Struggle to move" , "Pull hard; (sea) swell" , "Produce (a sigh); haul" , "Express" .)
