Memento of movement in central circles? (5)
I believe the answer is:
relic
'memento' is the definition.
(a relic is an antique or memento)
'movement in central circles?' is the wordplay.
'movement in' indicates an anagram (I've seen this in other clues).
'central' means to look at the middle letters.
The central letters of 'circles' are 'ircle'.
'ircle' anagrammed gives 'RELIC'.
'of' acts as a link.
(Other definitions for relic that I've seen before include "Something surviving but outdated" , "Venerated memento" , "Surviving ancient custom" , "Venerated remains" , "Heirloom" .)
