Tricked husband (a lecturer) (3,2)
I believe the answer is:
had on
'tricked' is the definition.
(to have someone on is to trick them)
'husband a lecturer' is the wordplay.
'husband' becomes 'h'.
'lecturer' becomes 'don' (don can mean an academic).
'h'+'a'+'don'='HAD ON'
(Other definitions for had on that I've seen before include "was sporting" , "Tricked" , "ragged" , "Was wearing; hoodwinked" , "Worn" .)
