Root Explanation

Unannounced → It is formed from "un-" (meaning not) and "announced" (from Latin "annuntiare", meaning to announce or proclaim). The word "unannounced" means not announced or made known beforehand.

Memory Tip

Think of 'not' ('un-') making something 'known' ('announced') — that's why unannounced means it wasn't made known beforehand.
