Etymology

The word "ethos" originates directly from Greek ἦθος (ēthos), meaning "custom, habit, or character." In ancient Greek philosophy, it referred to the moral and cultural disposition of a person or society. The term was adopted into English in the mid-19th century, retaining its core meaning of foundational beliefs or spirit. Unlike many loanwords, "ethos" preserves its original Greek spelling and structure, with the suffix "-os" functioning as a nominal ending.
