IPA: //ʌnˈsɜːrʧəbl//
KK: /ʌnˈsɜːrʧəbl/
Something that cannot be searched or examined; it is difficult or impossible to investigate or explore.
The depths of the ocean are often considered unsearchable due to their vastness and mystery.
Unsearchable → It is formed from "un-" (meaning not) and "search" (from Old English *siercan*, meaning to seek or look for) and "-able" (meaning capable of). The word "unsearchable" means not capable of being sought or looked for, often implying something that is too deep or complex to be understood or found.
Think of something that is 'not' ('un-') able to be 'sought' ('search') — that's why unsearchable means it cannot be found.
