Draw on a wimple, say (5)
I believe the answer is:
avail
'draw' is the definition.
The answer and definition can be both related to consumption as well as being verbs in their base form.
Perhaps there's a link between them I don't understand?
'on a wimple say' is the wordplay.
'on' is a charade indicator (letters next to each other).
'wimple say' becomes 'vail' (I can't explain this - if you can you should give a lot more credence to this answer).
'a' put next to 'vail' is 'AVAIL'.
Can you help me to learn more?
(Other definitions for avail that I've seen before include "See 3" , "Provide help; profit" , "Be of value to" , "Be of help or advantage" , "Be useful" .)
