IPA: //ʌnˈfɜːrnɪʃt//
KK: /ʌnˈfɜrnɪʃt/
Describing a space, usually a room or apartment, that does not have any furniture or decorations.
The apartment is unfurnished, so you will need to buy your own furniture.
Unfurnished → It is formed from "un-" (meaning not) and "furnish" (from Old French *furnir*, meaning to supply or equip). The word "unfurnished" means not supplied or equipped with furniture.
Think of 'not' ('un-') having 'furniture' — that's why unfurnished means a place without furniture.
