Peevish about England's cricket performance? (5)
I believe the answer is:
'peevish' is the definition.
(I know that peevish can be written as testy)
'about england's cricket performance?' is the wordplay.
'about' is an insertion indicator.
'england's' becomes 'e's'.
'cricket performance?' becomes 'tty' (I am not sure about this - if you are sure you should believe this answer much more).
'es' put within 'tty' is 'TESTY'.
Can you help me to learn more?
(Other definitions for testy that I've seen before include "Captious" , "bad temper" , "Easily irritated" , "Irascible" , "Short-tempered" .)
