IPA: /ˌɪnəˈproʊtʃəbl/
KK: /ɪnəˈproʊtʃəbl/
Someone or something that is difficult to approach or engage with, often due to being unfriendly or distant.
Despite her impressive qualifications, she seemed inapproachable during the interview.
Inapproachable → It is formed from "in-" (meaning not) and "approach" (from Old French *aprochier*, meaning to come near) and the suffix "-able" (meaning capable of). The word describes something that is not capable of being approached or reached.
Think of something that is 'not' ('in-') able to be 'come near' ('approach') — that's why inapproachable means it cannot be reached.
