Reach peer (5)
I believe the answer is:
equal
I believe this is a double definition.
'reach' is the first definition.
(thesaurus)
'peer' is the second definition.
(I know that peer can be written as equal)
(Other definitions for equal that I've seen before include "Numerically identical" , "Identical, add up to" , "What Orwell's animals were" , "Level" , "The same in all aspects" .)
