yon(adj., pron.)

Middle English, from Old English geon "that or those," referring to objects at a distance, "that one (or those) over there," from Proto-Germanic *jaino-, source also of Old Frisian jen, Old Norse enn, Old High German ener, Middle Dutch ghens, German jener, Gothic jains "that, you."

This is reconstructed to be from PIE pronominal stem *i- (source also of Sanskrit ena-, third person pronoun, anena "that;" Latin idem "the same," id "it, that one;" Old Church Slavonic onu "he;" Lithuanian ans "he").

By late 14c. as "farther, more remote" in reference to another. As an adverb from late 15c., a shortening of yonder.
