Subprincipal → It is formed from "sub-" (meaning under or below) and "principal" (from Latin "principalis", meaning chief or primary). The word "subprincipal" refers to someone who is under the chief or primary authority, often in a subordinate position.
Think of someone who is 'under' ('sub-') the 'chief' ('principal') — that's why a subprincipal is a person who assists or acts in place of the principal.
