Etymology
The word 'co-sponsor' is a modern English compound formed in the 20th century. The prefix 'co-', an assimilated form of the Latin 'com-' meaning 'with', was attached to the existing noun 'sponsor'. 'Sponsor' itself entered English from Latin, where a 'sponsor' was a guarantor or surety, one who makes a promise ('spondere'). The concept evolved from a legal or religious guarantor to a financial backer, especially for events or media. Therefore, 'co-sponsor' logically builds on this, denoting a partner who jointly provides the promise of support or funding.

Structure: co (together) + sponsor (supporter)
