Such humour befits a bit of a clown (3)
I believe the answer is:
low
'such humour befits a bit' is the definition.
I can't judge whether this defines the answer.
'of a clown' is the wordplay.
'of' indicates a hidden word.
'LOW' is hidden in the letters of 'clown'.
Can you help me to learn more?
(Other definitions for low that I've seen before include "Humble; dejected" , "Inferior, cow's call" , "Make a cow-like noise" , "Not high - that's mean" , "Opposite of high" .)
