Did you know?

The history of demeanor begins with a threat: the word has its roots in Latin minārī, “to threaten.” A form of that word was used in contexts having to do with driving animals—that is, impelling them to move—and from this word developed more recent ancestors having to do with leading, guiding, and behaving. By the 14th century, English had a adopted a word out of this lineage: the verb demean meaning “to conduct or behave (oneself) usually in a proper manner.” (Another demean, defined as “to lower in character, status, or reputation,” entered the language later by means of another root.) The noun demeanor was formed in the following century through the addition of the suffix -or.
