What does uninhabitable mean?
Uninhabitable means unfit for human habitation: a place cannot be lived in because its conditions, location, structure, or dangers make residence impossible or impractical. The word is especially common in discussions of planets, hostile environments, damaged buildings, extreme weather, and other settings where human survival would be difficult. It is more specific than uninhabited, which says only that no people currently live somewhere, and more emphatic than inhospitable, which suggests an unwelcoming atmosphere rather than a complete inability to support life. For example, a planet can be inhabited while being hostile, and a building can be uninhabited but still perfectly habitable once repaired or furnished. Uninhabitable is therefore a useful word when describing places that are not merely empty, but fundamentally unsuitable as human homes.

Where does uninhabitable come from?
Uninhabitable was formed in English by adding the negative prefix un- to inhabitable. Its base is connected to Latin inhabitare, meaning “to dwell in” or “to occupy,” which also underlies cognates such as inhabit, inhabitant, and habitation. The formation expresses the opposite of habitable: something that cannot be occupied by people as a residence.
