Bad-tempered domestic animal brought to Limerick university by worker (8)
I believe the answer is:
petulant
'bad-tempered' is the definition.
(I've seen this in another clue)
'domestic animal brought to limerick university by worker' is the wordplay.
'domestic animal' becomes 'pet' (animal kept in the home).
'brought to' is a charade indicator (letters next to each other).
'limerick university' becomes 'ul' (I can't justify this - if you can you should believe this answer much more).
'by' means one lot of letters go next to another.
'worker' becomes 'ant' (worker is a type of ant).
'pet'+'ul'+'ant'='PETULANT'
Can you help me to learn more?
(Other definitions for petulant that I've seen before include "Irritable, sullen" , "Pouting" , "Peevish, surly" , "Querulous and demanding" , "peevish impatience" .)
