Turn wife on part of foot (5)
I believe the answer is:
wheel
'turn' is the definition.
(thesaurus)
'wife on part of foot' is the wordplay.
'wife' becomes 'w'.
'on' says to put letters next to each other.
'part of foot' becomes 'heel' (I've seen this before**).
'w'+'heel'='WHEEL'
(Other definitions for wheel that I've seen before include "Cycle; swivel" , "Turn on axis" , "Circular frame on axle" , "Circular frame with spokes" , "Fly in a wide circle" .)
