Diminutive character good, the other half the size? (6)
I believe the answer is:
grumpy
'diminutive' is the definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?
'character good the other half the size?' is the wordplay.
I cannot quite understand how this works, but
'character' could be 'y' and 'y' is found within the answer.
'good' could be 'g' (abbreviation) and 'g' is found within the answer.
The remaining letters 'rump' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for grumpy that I've seen before include "Doc's irritable pal" , "Churlish" , "Peevish" , "Gloomy and irritable like sour old man" , "Ill-tempered and crabby" .)
