Describing something that is claimed or believed to be true, but may not actually be so.
The purported benefits of the new drug were questioned by many experts.
Purported is formed from "purport" (from Old French *purporter*, meaning to carry or convey) and the suffix "-ed" (indicating a past action or state). The word "purported" means claimed or alleged, often without proof, as if something is being carried or conveyed as true.
Think of something that is 'carried' or 'conveyed' as true, even if it may not be — that's what purported means.
