Some legumes can take a lot of chewing (3)
I believe the answer is:
gum
'take a lot of chewing' is the definition.
I can't judge whether this defines the answer.
'some legumes can' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'GUM' can be found hidden inside 'legumes can'.
Can you help me to learn more?
(Other definitions for gum that I've seen before include "Adhesive - eucalyptus" , "seal" , "surrounding roots of teeth?" , "Adhesive for chewing" , "Gingeva is its technical name" .)
