The act of removing furniture or equipment; the state of being without furnishings.
From disfurnish combined with the suffix -ment (which converts verbs to abstract nouns). It describes either the action of removing furnishings or the resulting bare condition.
Creating nouns from verbs using -ment (like 'disfurnishment' from 'disfurnish') was a standard Early Modern English pattern—but since the verb is now dead, the noun is too, leaving us with only historical text fossils.
