Servant blowing top working in inn (6)
I believe the answer is:
tavern
'inn' is the definition.
(thesaurus)
'servant blowing top working' is the wordplay.
'blowing top' means to remove the first letter.
'working' indicates an anagram.
'servant' with its first letter taken away is 'ervant'.
'ervant' is an anagram of 'TAVERN'.
'in' acts as a link.
(Other definitions for tavern that I've seen before include "An old English pub" , "An old inn, musically in the town" , "An old inn or hostelry" , "Old-fashioned word for pub" , "Tap-house" .)
