Root Explanation
Cofounded → It is formed from "co-" (meaning together) and "found" (from Old French *fonder*, meaning to establish or set up). The word "cofounded" means to establish something together with others.
Memory Tip
Think of 'together' ('co-') when you establish something ('found') — that's why cofounded means to establish something with others.
