I'm looking for a word that I think I heard somewhere before, and would like to use it, but for the life of me can't remember what it was exactly. It sounds similar to "epistemology" but epistemology is just a branch of philosophy. The word that I'm looking for is used to find background information, or the origin of something. For example What is the blank of your name. I ran through a few thesauruses, but so far no luck. So just curious if you guys are familiar with this.
