Make circular motions with part of foot (5)
I believe the answer is:
wheel
'make circular motions' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'with part of foot' is the wordplay.
'with' becomes 'w' (abbreviation).
'part of foot' becomes 'heel' (heel is a part of the foot).
'w'+'heel'='WHEEL'
Can you help me to learn more?
(Other definitions for wheel that I've seen before include "ring" , "Catherine -; gear -" , "Turn in a wide circle" , "Turn in a wide curve" , "- - of Fortune" .)
