A largely strident affair, but it bears fruit (7)
I believe the answer is:
avocado
'fruit' is the definition.
(I know that avocado is a type of fruit)
'a largely strident affair but it' is the wordplay.
I cannot really see how this works, but
'a' is within the answer.
'affair' could be 'do' (do is a kind of affair) and 'do' is located in the answer.
This explanation may well be incorrect...
'bears' acts as a link.
Can you help me to learn more?
(Other definitions for avocado that I've seen before include "Yellowish green" , "Alligator pear" , "slightly green" , "Fruit with large stone" , "Dull greenish colour" .)
