Conversation

Did you hear that cat sneak into the room?

No, it came in so noiselessly I didn't even notice!

That's impressive; I wish I could move around like that.

Right? It would be great to be noiseless when trying to surprise someone.

Synonyms & Antonyms

Root Explanation

Noiselessly → It is formed from "noise" (from Old French *noise*, meaning sound or disturbance) and "-less" (meaning without) and "-ly" (meaning in a manner). The word "noiselessly" means in a manner that is without sound or disturbance.

Memory Tip

Think of being 'without' ('-less') 'sound' ('noise') — that's why noiselessly means doing something in a quiet manner.
