I keep hearing people post that history is from 'his story', but I was under the impression history was from the Greek word historia which was roughly translated to acquire knowledge through investigation. It bothers me how random and contradictory Google has been with providing answers. Please help, thanks.
The idea that "history" comes from "his story" is meant as an illustrative tool that much of what is known about history, and what is taught about history, comes from the male perspective and concerns male spheres of influence, particularly in political and military history. It's not an etymological explanation (beyond folk etymology).
It definitely comes from the Greek word "istorìa" which means "research". The term was firstly used in a historic context by Erodoctus, who is considered one of the first (if not the first) western historian.
