What is the origin of saying hi as a greeting?
I was curious about something. Do you know anything about the origin of saying hi as a greeting?
Yes, I do! Saying "hi" as a greeting is believed to have originated from the word "hail". "Hail" was commonly used as a greeting in Old English and Middle English. Eventually, the word "hi" came to replace "hail" as a more informal greeting.
