I found this really cute dress at the thrift store yesterday.

Nice! Is it a classic style or something more modern?

It's definitely more of a classic, and it's even undated — no tag or anything.

That sounds perfect! Those timeless pieces are always a great find.

Synonyms & Antonyms

Root Explanation

Undated → It is formed from "un-" (meaning not) and "date" (from Latin "data", meaning something given or assigned). The word "undated" means not assigned a specific date or time.

Memory Tip

Think of 'not' ('un-') having a 'specific time' ('date') — that's why undated means something that doesn't have a date assigned.
