Pedal parts (4)
I believe the answer is:
feet
'parts' is the definition.
(foot is a kind of part)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for feet that I've seen before include "Lower extremities" , "Linear Units of a third of a yard" , "Unit used to measure" , "Body parts; lengths" , "Three of these in yard" .)
