Girl helping with the washing? (3)
I believe the answer is:
peg
'girl' is the definition.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for peg that I've seen before include "Kind of pin for hanging clothes" , "Short pin or bolt" , "The woman" , "The girl to hold a hat" , "The girl to hang your hat on" .)
