IPA: //ʌnˈɛɡzɛmpld//
KK: /ʌnˈɛkˌsɛmpəld/
Something that has never been seen or done before; unique and without any previous example.
The artist created an unexampled masterpiece that left everyone in awe.
Unexampled → It is formed from "un-" (meaning not) and "exampled" (derived from "example" which comes from Latin "exemplum", meaning a model or pattern). The word "unexampled" means not having an example or unprecedented.
Think of 'not' ('un-') having a 'model' or 'pattern' ('exampled') — that's why unexampled means something that has no precedent.
