Bad-tempered type of dog, dog men exercised outside university (10)
I believe the answer is:
curmudgeon
'bad-tempered type' is the definition.
'of dog dog men exercised outside university' is the wordplay.
I cannot quite understand how this works, but
'of' could be 'o' and 'o' is present in the answer.
'dog' could be 'cur' (cur is a kind of dog) and 'cur' is found in the answer.
'university' could be 'u' and 'u' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for curmudgeon that I've seen before include "He's surly" , "Bad-tempered person" , "Dunce or mug (anag) - grumbler" , "Meldrew, say" , "grump" .)
