Draws, we hear, little piggies for children (4)
I believe the answer is:
toes
'little piggies for children' is the definition.
I can't tell whether this defines the answer.
'draws we hear' is the wordplay.
'draws' becomes 'tows' (towing is a kind of drawing).
'we hear' shows a homophone (sound like).
'tows' sounds like 'TOES'.
Can you help me to learn more?
(Other definitions for toes that I've seen before include "Lower digits" , "Foot digits" , "Divisions of foot front" , "What Pobble lacked (Lear)" .)
