Way to entertain little fool, perhaps (5)
I believe the answer is:
sweet
'fool perhaps' is the definition.
(I know that fool is a type of sweet)
'way to entertain little' is the wordplay.
'way' becomes 'st' (abbreviation for street).
'to entertain' means one lot of letters goes inside another.
'little' becomes 'wee' (similar in meaning).
'st' placed around 'wee' is 'SWEET'.
(Other definitions for sweet that I've seen before include "(see 15 across) A Chinese sauce" , "S [SWEET] , basically" , "Kind" , "Sugary - but might be tart!" , "Cute" .)
