Morphology

Archiannelida = Annelida (semi-transparent) = archi + annelida + archi

Formally composed of the combining prefix 'archi-' and the taxonomic name 'Annelida'; the formation is clear for readers familiar with scientific naming but the prefix is specialized and may not be known to general learners.

Etymology

Archiannelida comes from two parts: archi- meaning 'first' or 'ancient', as in archenemy, and annelida meaning 'ringed worm' or 'little ring'. So Archiannelida literally means 'ancient ringed worms', which fits its use for a group of small, primitive marine worms.
