Maybe stone wife shed to reveal figure? (5)
I believe the answer is:
eight
'figure?' is the definition.
(I know that eight is a type of digit)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for eight that I've seen before include "One over it and you were drunk, it was said" , "Number (with pieces?)" , "Number for rowers" , "Number (of oarsmen?)" , "Pints in gallon" .)
