Company agent sorted or related (7)
I believe the answer is:
cognate
'related' is the definition.
(similar in meaning)
'company agent sorted' is the wordplay.
'company' becomes 'co' (abbreviation).
'sorted' is an anagram indicator.
'agent' with letters rearranged gives 'gnate'.
'co'+'gnate'='COGNATE'
'or' is the link.
(Other definitions for cognate that I've seen before include "from the same root" , "Related, having same source" , "Associated" , "with similar origins" , "Of the same family" .)
