The odd quiet president (5)
I believe the answer is:
trump
'president' is the definition.
(Donald Trump)
'the odd quiet' is the wordplay.
I cannot quite see how this works, but
'odd' could be 'rum' (I've seen this before) and 'rum' is present in the answer.
'quiet' could be 'p' (music symbol for 'piano') and 'p' is present in the answer.
A single letter 't' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for trump that I've seen before include "High card" , "take trick" , "The last one to announce" , "club perhaps" , "Card beating other suits" .)
