Morphology

subkingdom = kingdom (transparent) = sub + kingdom

The productive prefix 'sub-' meaning 'below' combines with 'kingdom' to indicate a subordinate taxonomic rank, a directly derivable technical term.

Etymology

Subkingdom begins with sub- meaning 'under' and ends with kingdom meaning 'a land ruled by a king' or 'a large group'. So in biology a subkingdom is like a smaller kingdom under a bigger one, a group below a kingdom but above a phylum.
