Sticky exudation from legumes (3)
I believe the answer is:
gum
'sticky exudation' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'from legumes' is the wordplay.
'from' indicates a hidden word.
'GUM' can be found hidden inside 'legumes'.
Can you help me to learn more?
(Other definitions for gum that I've seen before include "Stuff to chew" , "Leaving body" , "Adhesive - eucalyptus" , "Glue; jelly-like sweet" , "Gingeva is its technical name" .)
