To remove furniture or equipment from a place, or to leave something unequipped.
From dis- (meaning 'remove' or 'reverse') combined with furnish (from Latin fornire, meaning 'to supply'). This emerged in Early Modern English to describe the opposite of furnishing a space.
This word is almost completely obsolete now, but it shows that in earlier English, you could form verbs to describe removing almost anything—'disfurnish' a room, 'disarm' a person, 'dismantle' a device—revealing a more productive verb-creation system.
