Morphology

Metazoa = meta + zoa

Although the word can be segmented into the classical prefix meta- and the Greek root zoa 'animals', the taxonomic meaning 'multicellular animals' is specialized and not directly inferable for most learners.

Etymology

The word Metazoa comes from Greek parts meta- meaning 'beyond' and zoa meaning 'animals', similar to the everyday word zoo. So Metazoa means 'animals beyond single cells' and today it names all animals made of many cells, not single-celled animals.
