Who made the word hey?

The word "hey" is so old that its origins are difficult to trace precisely.

Here's what we know:

* It's Proto-Germanic: The word "hey" comes from the Proto-Germanic word "hai," which was used as an interjection to get someone's attention.

* Old English: In Old English, the word evolved into "hā" and was still used for getting someone's attention.

* Modern English: Over time, the "hā" transformed into "hey" and its use expanded to become a more general greeting or exclamation.

Therefore, no single person "made" the word hey. It's a word that evolved over centuries of language use, starting with our ancestors in the Proto-Germanic period.
