Where you'll get a bit of thunder by night (5)
I believe the answer is:
derby
'where you'll get a bit' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'of thunder by night' is the wordplay.
'of' says the answer is hidden in the clue.
'DERBY' can be found hidden inside 'thunder by night'.
Can you help me to learn more?
(Other definitions for derby that I've seen before include "Cathedral city on the River Derwent" , "close match?" , "Commotion" , "confrontation between neighbours" , "20 horse 12" .)
