Circled right piece in dictionary (7)
I believe the answer is:
orbited
'circled' is the definition.
(orbiting is a kind of circling)
'right piece in dictionary' is the wordplay.
'right' becomes 'r' (common abbreviation).
'piece' becomes 'bit' (synonyms).
'in' indicates putting letters inside.
'dictionary' becomes 'OED' (Oxford English Dictionary).
'r'+'bit'='rbit'
'rbit' going into 'oed' is 'ORBITED'.
(Other definitions for orbited that I've seen before include "Moved like curved path of planet" , "Went around" , "Travelled in curved path like planet" , "Travelled on circular path like satellite" , "Went round - to bride (anag)" .)
