As 'master', receive too much (3,4)
I believe the answer is:
get over
'as master' is the definition.
'get over' can be an answer for 'master' (synonyms). I'm unsure of the 'as' bit.
'receive too much' is the wordplay.
'receive' becomes 'get' (synonyms).
'too much' becomes 'over' (I've seen this before).
'get'+'over'='GET OVER'
Can you help me to learn more?
(Other definitions for get over that I've seen before include "Deal with successfully, improve in health" , "Clear" , "master?" , "Recover" .)
