co-authored

The word 'co-authored' is a modern compound formed by attaching the Latin-derived prefix 'co-' to the verb 'authored'. The prefix 'co-', a variant of 'com-', originates from the Proto-Indo-European root kom, meaning 'beside' or 'near', which evolved in Latin to signify accompaniment and joint action. The core verb 'author' stems from the Latin 'auctor', meaning 'originator' or 'promoter', which itself derives from 'augere' (to increase, originate). Therefore, the literal construction 'written together' perfectly captures the modern abstract meaning of joint creation, reflecting a transparent and logical semantic evolution where ancient concepts of partnership and origination combine to describe collaborative intellectual work.
