Men tucked into mostly ripe fruit (7)
I believe the answer is:
morello
'fruit' is the definition.
(morello is a kind of fruit)
'men tucked into mostly ripe' is the wordplay.
'men' becomes 'or' (I've seen this in other clues).
'tucked into' means one lot of letters goes inside another.
'mostly' means to remove the last letter.
'ripe' becomes 'mellow' ('mellow' can be similar in meaning to 'ripe').
'mellow' with its final letter removed is 'mello'.
'or' going within 'mello' is 'MORELLO'.
(Other definitions for morello that I've seen before include "Type of cherry" , "Dark red cherry" , "cherries" , "Small, dark, sour cherry" , "Cherry's" .)
