Ye comes from Old English ġē ('you', nominative plural), from Proto-Germanic *jīz ('you'). The 'the' sense arises from a misreading of the thorn letter (þ) printed as y. In current use it is a pronoun and det meaning "you (archaic plural or formal), or an old form of the". That sense is explained by the older material without requiring a speculative semantic step: the inherited or borrowed base supplies the field of meaning, while the English formation fixes its modern role. The history is mainly one of transmission into English, with the older form and sense carried through borrowing or adaptation. The historical chain includes Old English ġē and Proto-Germanic *jīz. Related English forms include you, your, and thee. For dictionary purposes, the important point is the continuity between the older form, the route into English, and the present lexical sense.
