Charge around, returning to participate in revolution (6)
I believe the answer is:
rotate
'participate in revolution' is the definition.
I can't tell whether this defines the answer.
'charge around returning to' is the wordplay.
'charge' becomes 'rate' (rate is a kind of charge).
'around' means one lot of letters goes inside another.
'returning' says the letters should be written backwards.
'to' written backwards gives 'ot'.
'rate' placed around 'ot' is 'ROTATE'.
Can you help me to learn more?
(Other definitions for rotate that I've seen before include "Spin round" , "Turn around an axle, swivel" , "Pivot" , "'Er, to a T? (anag)" , "Revolve" .)
