Exceptionally big for example in degree (4)
I believe the answer is:
mega
'exceptionally big' is the definition.
'mega' can be an answer for 'big' (I've seen this before). I am not sure about the 'exceptionally' bit.
'example in degree' is the wordplay.
'example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'in' indicates putting letters inside.
'degree' becomes 'MA' (Master of Arts is a type of degree).
'eg' going within 'ma' is 'MEGA'.
'for' is the link.
Can you help me to learn more?
(Other definitions for mega that I've seen before include "Game (anag) - excellent" , "Game (anag) -- great" , "Big" , "Very large (prefix)" , "wicked" .)
