An equal; a peer or person of the same rank, status, or ability as another.
From Old French comper (com- 'with' + per 'equal'), from Latin par 'equal'. Entered English in the 13th century from Romance language influence.
Compeer perfectly captures a concept that modern English muddles—it means not just 'equal' but specifically 'one who stands beside you as an equal,' implying mutual recognition of worth rather than imposed hierarchy.
