Is ordi an NFT?

Could you please clarify whether "Ordi" is indeed an NFT, or a Non-Fungible Token? I'm curious to understand its classification within the cryptocurrency and digital asset landscape. If it is an NFT, I'd like to know what makes it unique and what kind of value it represents. If not, could you elaborate on what Ordi actually is and how it differs from NFTs? Your insight would be greatly appreciated in helping me gain a clearer understanding of this potentially emerging asset.
