Definition

Not having oxygen or being without oxygen.

Conversation

Did you hear about that new dive site they discovered?

Yeah, I heard it’s pretty amazing, but it can be oxygenless at certain depths.

That sounds a bit risky, though.

Definitely! I’d want to be careful and make sure I have the right gear.

Synonyms & Antonyms

Root Explanation

Oxygenless → It is formed from "oxygen" (from Greek "oxus" meaning acid and "genes" meaning producer) and "-less" (meaning without). The word "oxygenless" means without oxygen.

Memory Tip

Think of 'oxygen' as the essential element for life, and '-less' means lacking it — so 'oxygenless' describes a state of being without oxygen.
