Why is mana called mana?

Could you please explain to me the etymology behind the term 'mana'? I'm curious to know why it's specifically called 'mana' and what the origin of this word might be. Is it derived from a specific culture or language? Or does it have some deeper, symbolic meaning? I'm fascinated by the naming conventions in the cryptocurrency world and how they often reflect unique cultural or historical references. Thank you for your insight!
