Sweet stick gathering last of sherbet (4)
I believe the answer is:
cute
'sweet' is the definition.
(cute can mean sweet or adorable)
'stick gathering last of sherbet' is the wordplay.
'stick' becomes 'cue' (I've seen this before).
'gathering' is an insertion indicator (gather can mean to acquire or bring in).
'last of' indicates one should take the final letters.
The final letter of 'sherbet' is 't'.
'cue' enclosing 't' is 'CUTE'.
(Other definitions for cute that I've seen before include "Clever - attractive" , "Precious" , "Small, delightful" , "Daintily pleasing" , "Attractive or ingenious" .)
