Charming little street outside (5)
I believe the answer is:
sweet
'charming' is the definition.
(thesaurus)
'little street outside' is the wordplay.
'little' becomes 'wee' (similar in meaning).
'street' becomes 'st' (abbreviation).
'outside' indicates putting letters inside (some letters go outside others).
'wee' put into 'st' is 'SWEET'.
(Other definitions for sweet that I've seen before include "Afters" , "Kind" , "Ewes cycle it (anag) -- herb (myrrh)" , "bon-bon" , "Humbug!" .)
