IPA: /ˌʌn.əˈdʌl.tə.reɪ.tɪd/
KK: /ʌnəˈdʌltəreɪtɪd/
Something that is pure and not mixed with anything else; it is complete and absolute without any inferior substances.
The juice was unadulterated, made from fresh fruits without any additives.
Unadulterated → It is formed from "un-" (meaning not), "adulterare" (meaning to corrupt or make impure), and the suffix "-ated" (indicating a state or condition). The word "unadulterated" means in a state that is not corrupted or impure, indicating purity.
Think of 'not' ('un-') corrupting or making something impure ('adulterare') — that's why unadulterated means pure.
