Husband turning tipsy, not mesmerising person (9)
I believe the answer is:
hypnotist
'mesmerising person' is the definition.
(I've seen this before)
'husband turning tipsy not' is the wordplay.
'husband' becomes 'h' (abbreviation).
'turning' indicates an anagram.
'tipsy'+'not'='tipsynot'
'tipsynot' is an anagram of 'ypnotist'.
'h'+'ypnotist'='HYPNOTIST'
(Other definitions for hypnotist that I've seen before include "Mesmerising person" , "One who mesmerises" , "Mesmeriser" , "charmer" , "stage entertainer" .)
