IPA: //ʌnˈlɪvəbl//
KK: /ʌnˈlɪvəbl/
Not suitable for living in; a place that cannot be lived in due to poor conditions or safety issues.

Comparative: more unlivable
Superlative: most unlivable
Unlivable → It is formed from "un-" (meaning not) and "livable" (from Latin "vita" meaning life, combined with the suffix "-able" meaning capable of). The word "unlivable" means not capable of supporting life or unsuitable for living.
Think of 'not' ('un-') being added to 'capable of life' ('livable') — that's why unlivable means not suitable for living.
