Etymology

Origin of concomitant

First recorded in 1595–1605; from Latin concomitant- (stem of concomitāns, present participle of concomitārī ), equivalent to con- con- + comit- (stem of comes ) comes + -ant- -ant

Explanation

Concomitant means "accompanying." If you run into someone that you have a crush on, you might feel nervousness with a concomitant forgetfulness. Concomitant is one of those Latin-based words you can break down into little pieces: con means "with," and comit means "companion." So something that is concomitant is like the companion of the main event. If you start training really hard at the gym, the main effect is that you become stronger, but there are concomitant effects, like better circulation, or a rosy glow, or getting happy from all those endorphins you’re releasing.
