Is osmosis a dex?

Excuse me, could you please clarify whether osmosis is considered a decentralized exchange, or DEX, in the realm of cryptocurrency? I'm a bit confused about the terminology, and I'd like to ensure I have a clear understanding of how it fits into the broader cryptocurrency ecosystem. Could you elaborate on the specifics of osmosis, its functionality, and whether it aligns with the typical characteristics of a DEX? Your insights would be greatly appreciated.
