Discompose is a verb that means to disturb or agitate from a calm state. 

Compose is a Latin-based word that’s been around since the late Middle English period and it  means ’to order or arrange.’ When we add the prefix D-I-S to it, we get our word of the day, which means to remove or disturb that order. Here’s an example:

Things were going well at the party until those hoodlums came in to discompose the environment. Soon, all that sense of calm just evaporated and we had a gang fight on our hands.
