: the distinguishing character, sentiment, moral nature, or guiding beliefs of a person, group, or institution

Did you know?

In Greek, ēthos means “custom” or “character.” As originally used by Aristotle, it referred to a person’s character or personality, especially with respect to a balance between passion and caution. In English, ethos is used today to refer to the practices or values that distinguish one person, organization, or society from others. In rhetoric, ethos is often studied alongside pathos and logos as a technique to successfully persuade an audience. Related terms in the English language include ethics (“a branch of philosophy dealing with what is morally right or wrong”) and ethology (“a branch of knowledge dealing with human character and with its formation and evolution”).
