Trump fervour rekindled by following (8)
I believe the answer is:
overruff
'trump' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'fervour rekindled by following' is the wordplay.
I cannot quite see how this works, but
an anagram of 'fervour' is 'overruf' which is located in the answer.
'following' could be 'f' (used when citing page numbers etc) and 'f' is found within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for overruff that I've seen is " play a higher trump".)
