Satan is only a title, not a name
ADVERSARY/OPPOSER/ACCUSER: satan. Masculine noun (Strong’s 7854). Verb: To accuse, to oppose, to be adversarial (Strong’s 7853).
Root: שָׂטָן
Sounds like: saTahn
Somehow it has become the name of the Evil One, although it was never intended to be. Satan simply means adversary or opposer. It may come as a shock to find out that some very good people were called a satan.
Ha-Satan
So how did this Hebrew word meaning adversary or opposer turn into the name of the Evil One? Well, actually, it was never meant to be a name, only a title. Ha-Satan means The (Ha) Adversary (Satan)/The Accuser/The Opposer. It is a title (not a name) given to the Big Bad One
