Great amount of bigotry (3)
I believe the answer is:
big
'great' is the definition.
(I know that great can be written as big)
'amount of bigotry' is the wordplay.
'amount' becomes 'B' (B is an example).
'of bigotry' becomes 'ig' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'b'+'ig'='BIG'
Can you help me to learn more?
(Other definitions for big that I've seen before include "Massive" , "London bell" , "Of considerable size" , "Important" , "Large or substantial" .)
