IPA: /ɪnˈtɒlərəbli/

In a way that is too bad or severe to be accepted or tolerated.

Intolerably → It is formed from "in-" (meaning not) and "tolerare" (meaning to bear or endure) combined with the suffix "-ably" (meaning in a manner). The word "intolerably" means in a manner that cannot be endured or tolerated.
Think of 'not' ('in-') being able to 'bear' ('tolerare') something — that's why intolerably means something that cannot be endured.
