A crafty offer? (6)
I believe the answer is:
tender
'offer?' is the definition.
(tender can mean to offer something)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for tender that I've seen before include "Offer; ferry boat" , "easily damaged" , "Not hardy (but it may be legal)" , "requiring careful handling" , "Compassionate - sore" .)
