I watched that new movie last night, and it was pretty lackluster overall.

Really? I heard it was supposed to be exciting.

Yeah, the storyline was dull and the characters were lackluster too.

Synonyms & Antonyms

Root Explanation

Lackluster → It is formed from "lack" (from Old English *lacan*, meaning to be without) and "luster" (from Latin *lustrare*, meaning to shine or illuminate). The word "lackluster" describes something that is without shine or brilliance, indicating dullness or mediocrity.

Memory Tip

Think of being 'without' ('lack') shine or brightness ('luster') — that's why lackluster means dull or uninspired.
