IPA: /ˌʌnəˈsɪmɪləbəl/
KK: /ʌnəˈsɪmɪləbəl/
Unable to be absorbed or integrated into a larger group or society.
Some cultures are considered unassimilable due to their strong traditions and beliefs.
Unassimilable → It is formed from "un-" (meaning not), "assimilare" (from Latin, meaning to make similar or to absorb), and "-able" (meaning capable of). The word describes something that is not capable of being made similar or absorbed into a group or system.
Think of 'not' ('un-') being able to 'absorb' or 'make similar' ('assimilare') — that's why unassimilable means something that cannot be absorbed or integrated.
