To make something no longer occupied; to vacate or clear a space or position.
From dis- (to reverse or remove) + occupy (to fill or take up space), from Latin occupare. The dis- prefix creates the opposite action of occupying.
Like 'disoccupied,' this verb is virtually obsolete—English speakers use 'vacate' or 'evacuate' instead. It's a perfect example of how English naturally selects one word from multiple possibilities, and dis- versions of common words tend to lose out to more established alternatives.
