IPA: /ɪmˈpɑːrʃəlɪti/
KK: /ɪmˈpɑrʃəlɪti/
The quality of treating all people and groups equally without favoritism or bias.
The judge's impartiality ensured a fair trial for both parties.
Impartiality is formed from "im-" (meaning not) and "partial" (from Latin "partialis", meaning relating to a part). The suffix "-ity" (meaning the state or quality of) indicates the condition of being not partial. Thus, impartiality refers to the state of being unbiased or fair, not favoring one side over another.
Think of 'not' ('im-') being 'partial' — that’s why impartiality means being fair and unbiased.
