An amphibian, say, with foot digits (4)
I believe the answer is:
toed
'an amphibian say with foot digits' is the definition.
I can't tell whether this defines the answer.
'an amphibian say' is the wordplay.
'an amphibian' becomes 'toad' (toad is a kind of amphibian).
'say' shows a homophone (sound like).
'toad' is a homophone of 'TOED'.
Can you help me to learn more?
(Other definitions for toed that I've seen before include "inferior terminal projections" , "Kicked" .)
