Morphology
The term is directly compositional: 'subkingdom' names the taxonomic rank and 'Parazoa' is the taxon label, so the phrase simply denotes the taxon Parazoa at the subkingdom rank (i.e., the group of simple multicellular organisms/sponges). Although technical, this follows standard, cross-linguistic taxonomic naming conventions, so a learner who knows both constituents can infer the meaning.
Etymology
Subkingdom Parazoa comes from the word parts para meaning 'beside' and zoa meaning 'animals', giving the picture of life that sits beside true animals. It now names a small group of very simple animals, like sponges, that have less specialized cells and do not form 'true tissues'.
