Describing something that has not been observed or recorded.
The unnoted details of the event were later revealed in the investigation.
Unnoted → It is formed from "un-" (meaning not) and "noted" (from Latin "notare", meaning to mark or note). The word "unnoted" means not marked or not observed.
Think of 'not' as a way to indicate something is 'not marked' or 'not observed' — that's what unnoted means.
