IPA: /ʌnˈnoʊəbl/
KK: /ʌnˈnoʊəbl/
Something that cannot be known or understood, often because it is beyond human experience or comprehension.
The concept of infinity is often seen as an unknowable idea.
Unknowable → It is formed from "un-" (meaning not) and "know" (from Old English "cnāwan", meaning to know) and "-able" (meaning capable of). The word "unknowable" means not capable of being known or impossible to know.
Think of 'not' ('un-') being added to 'know' — this helps you remember that 'unknowable' refers to something that cannot be known.
