Show anger when success is not allowed (3,3)
I believe the answer is:
hit out
'show anger' is the definition.
Both the answer and definition are verbs in their base form.
Maybe they are linked in a way I don't understand?
'success is not allowed' is the wordplay.
'success' becomes 'hit' (hit is a kind of success).
'is not allowed' becomes 'out' (I've seen this before).
'hit'+'out'='HIT OUT'
'when' acts as a link.
Can you help me to learn more?
(Other definitions for hit out that I've seen before include "Attack verbally" , "Be severely critical of" , "Launch a verbal attack" , "Aim a blow, perhaps in self-defence" , "Throw a punch" .)
