IPA: //ʌnˈeɪliənəbl//
KK: /ʌnˈeɪliənəbl/
Something that cannot be taken away or separated from a person; it is a right or quality that is inherent and cannot be surrendered.
The right to free speech is considered an unalienable right in many democracies.
Unalienable → It is formed from "un-" (meaning not) and "alienable" (from Latin "alienabilis", meaning able to be transferred or surrendered). The word "unalienable" means something that cannot be taken away or transferred, emphasizing its inherent and permanent nature.
Think of 'not' ('un-') being able to be 'transferred' ('alienable') — that's why unalienable means something that cannot be taken away.
