KK: /ʌˈneɪmənbəl/
Not willing to be influenced or controlled; resistant to suggestions or requests.

Unamenable → It is formed from "un-" (meaning not) and "amenable" (from Latin "aminabilis", meaning capable of being led or brought). The word "unamenable" means not capable of being led or brought to a particular course of action.
Think of 'not' ('un-') being able to be 'led' or 'brought' ('amenable') — that's why unamenable means not willing to be led.
