Speaks out and draws digits (4)
I believe the answer is:
toes
'digits' is the definition.
(toe is a kind of digit)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for toes that I've seen before include "What Pobble lacked (Lear)" , "Divisions of foot front" , "Foot digits" , "Lower digits" .)
