Reward for honoured folk is said to be fiddle (6)
I believe the answer is:
meddle
'reward' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for meddle that I've seen before include "Interfere, butt in" , "Intrude in other people's affairs" , "Interfere unnecessarily" , "Interfere in other people's business" , "Potter" .)
