The phrase "die hard" is believed to have originated in the 17th century, with the separate words "die" and "hard" already existing at that time.
The term "die" stems from the Middle English word "dyen", which was derived from the Old English word "deogan", meaning "to pass away" or "to perish". Over time, it evolved into the modern English verb "to die", referring to the act of dying.
On the other hand, "hard" originates from the Old English word "heard", which denotes something that is difficult or resistant. It can also mean strong or firm in certain contexts.
