Corresponds with peers (6)
I believe the answer is:
equals
I believe this clue is a double definition.
'corresponds with' is the first definition.
(correspond with can mean to equal or equate to)
'peers' is the second definition.
(I know this)
(Other definitions for equals that I've seen before include "Those with the same status, rights, etc." , "They're at the same level" , "Corresponds to" , "Persons of the same rank, for instance" , "Is identical in quantity, value" .)
