The word "endward" is a rare and obsolete term with a relatively obscure etymology. It is derived from the Middle English word "endewarde", which combines two elements: "end" and "-ward".
The term "end" comes from the Old English word "end", meaning "end" or "limit". The Old English "end" has its roots in the Proto-Germanic word "*andja", which carries the same meaning.
The second element, "-ward", is a suffix indicating direction or movement toward a specific place. It is derived from the Old English "-weard", which can be traced back to the Proto-Germanic "*-warda".
Together, "endward" essentially means "towards the end" or "in the direction of the end". However, this term is no longer in common usage and is considered archaic.
