Etymology
The word is a modern compound formed in English. The prefix 'co-', an assimilated form of the Latin prefix 'com-' (with, together), was attached to the existing English noun 'founder', which itself entered English via Anglo-Norman French 'founder'. The French term derives from Latin 'fundator', meaning 'one who lays a foundation', from the verb 'fundare' (to found), based on 'fundus' (bottom, base). Thus, 'co-founder' literally and logically means 'a joint founder', one who participates with others in laying the foundational base of an enterprise. This construction follows a productive pattern in English for indicating shared roles or actions.
