Work involved in diplomacy repelled Trump, perhaps (3,3)
I believe the answer is:
top cat
'trump perhaps' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'work involved in diplomacy repelled' is the wordplay.
'work' becomes 'op' (short for opus).
'involved in' is an insertion indicator.
'diplomacy' becomes 'tact' (tact can mean diplomacy or sensitivity).
'repelled' says the letters should be written in reverse.
'tact' back-to-front is 'tcat'.
'op' going within 'tcat' is 'TOP CAT'.
Can you help me to learn more?
(Another definition for top cat that I've seen is " CAT".)
