Full expanded form of IOTA blockchain?

 Well.... I always used to look for the expanded form of IOTA blockchain but could never get the answer. But today I got the same finally vide a chat as produced below:

" it's not an acronym, but it stands for the smallest unit possible in the greek alphabet, as with IOTA also micropayments are possible, e.g. 0.000001 cent. IOTA is engineered completely different than a traditional blockchain, but the IOTA Foundation is one of the leading orgs for DLT research globally, pioneering the DAG (directed acyclic graph) since 2016. The DAG enables parallel access to the DLT. IOTA is designing a green, secure, feeless and highly scalable DLT, without the negative "issues" of blockchain. This also makes it very suitable for data-driven scenarios like DID. Organizations also do not need to buy/hold cryptocurrency"
