Did You Know?

There's a long trail from Latin minari (which means "to threaten" and has been connected to the threatening cries of cattle drivers) to English demeanor. Along the way, we first encounter Latin minare; it means "to drive" and was once used specifically of driving animals for herding. From there, the path leads us to Anglo-French, where we pass by mener (to lead) and then demener (to conduct). Next comes Middle English demenen and then Modern English demean, both meaning "to conduct (oneself) in a certain manner." And, finally, we take one last step, and add the suffix -or to demean to get demeanor.
