Clink glasses tiresomely? Not entirely (4)
I believe the answer is:
stir
'clink' is the definition.
(thesaurus)
'glasses tiresomely? not entirely' is the wordplay.
'not entirely' indicates a hidden word.
'STIR' is hidden within 'glasses tiresomely'.
(Other definitions for stir that I've seen before include "can > go forth" , "beat" , "Uproar" , "Move; wake" , "College" .)
