Epistemological psychology
The term episteme is related to the Greek word επιστήμη, which translates literally as "standing near or by that which causes" but is often simplified as "knowledge" or "science". By ignoring ego interests the core impetus or the essence of a deed, real or imagined, is recovered.
Etymology
In linguistics, the term "etymon" refers to a word or morpheme (e.g., stem or root) from which a later word derives. For example, the Latin word "candidus", which means "white", is the etymon of English "candid".
