It turns out that we might have been fooling ourselves with the “hi” to “hey” controversy.

We were discussing when the word “hey” became the new “hi” and wondering if this was a Friendsism creeping into the language.

So “hi” was originally derived from “hey” and both were a call for attention; in North America, “hi” became a friendly greeting in the 19th century; and in the 20th “hey” became “hi,” even though the OED doesn’t acknowledge that yet.
