I'm engaged in work with corporation -- most favourable outcome (7)
I believe the answer is:
optimum
'most favourable outcome' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'i'm engaged in work with corporation' is the wordplay.
'engaged in' indicates putting letters inside.
'work' becomes 'op' (abbreviation for opus**).
'with' means one lot of letters go next to another.
'corporation' becomes 'tum' (I've seen this before).
'op'+'tum'='optum'
'im' inserted into 'optum' is 'OPTIMUM'.
Can you help me to learn more?
(Other definitions for optimum that I've seen before include "Most favourable point" , "The best possible" , "top condition" , "The most favourable condition" , "model" .)
