Conversation

I heard some rumors about the new project, but they seem a bit unfounded.

Yeah, I don't think there's any real evidence to support those claims.

Totally! We should focus on what we know instead of believing those unfounded stories.

Root Explanation

Unfounded → It is formed from "un-" (meaning not) and "founded" (from the Old French *fonder*, meaning to establish or set up). The word "unfounded" means not established or lacking a basis in fact.

Memory Tip

Think of something that is 'not' ('un-') 'established' ('fonder') — that's why unfounded means lacking a solid basis.
