IPA: /ʌnˈænsərəbəl/
KK: /ʌnˈænsərəbəl/
Something that cannot be answered or responded to, often because it is too difficult or clear to dispute.
The lawyer presented an unanswerable argument that left the jury in awe.
Unanswerable → It is formed from "un-" (meaning not) and "answer" (from Old English "andswaru", meaning a response or reply) and "-able" (meaning capable of). The word "unanswerable" means not capable of being answered or responded to.
Think of 'not' ('un-') being added to 'response' ('answer') and 'capable of' ('-able') — this helps you remember that unanswerable means something that cannot be responded to.
