Series sounds delightful (5)
I believe the answer is:
suite
'series' is the definition.
(thesaurus)
'sounds delightful' is the wordplay.
'sounds' shows a homophone (sound like).
'delightful' becomes 'sweet' (I've seen this before).
'sweet' sounds like 'SUITE'.
(Other definitions for suite that I've seen before include "Musical composition" , "Train; set of rooms" , "Extensive accommodation" , "Collection of pieces" , "Compensate for (faults)" .)
