Doorplate → It is formed from "door" (from Old English *dor*, meaning entrance or opening) and "plate" (from Old French *plate*, meaning flat or broad object). The word "doorplate" refers to a flat object placed on or near a door, often for identification or decoration.
Think of a 'door' as an entrance and a 'plate' as a flat object — a doorplate is something flat that you place near the entrance.
