Where did the root word from dialog come from?

The root word for "dialog" comes from the Greek word "διάλογος" (diálogos), which means "conversation" or "discourse."

The word is formed from the combination of two Greek words:

* διά (dia) meaning "through," "across," or "between"

* λόγος (logos) meaning "word," "speech," or "reason"

Therefore, "diálogos" literally translates to something like "speaking through/between" or "a conversation between."
