Amount of fish bearing small amount of eggs (7)
I believe the answer is:
nestful
'amount of eggs' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'amount of fish bearing small' is the wordplay.
I cannot really understand how this works, but
'amount' could be 't' (T is an example) and 't' is found within the answer.
'bearing' could be 'ne' and 'ne' is found in the answer.
'small' could be 's' (abbreviation - e.g. clothes size) and 's' is found within the answer.
The remaining letters 'ful' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for nestful that I've seen before include "clutch" , "Brood" , "Crowded home (for birds or vipers)" , "A lot of flyers" .)
