IPA: //ʌnˈpærəˌlɛld//
KK: /ʌnˈpærəˌlɛld/
Something that is unmatched or has no equal in quality or kind.
Her talent for music is unparalleled, making her stand out among her peers.
Unparalleled → It is formed from "un-" (meaning not) and "paralleled" (from the root "parallel" which comes from Greek "parallelos", meaning side by side). The word "unparalleled" means not having a parallel or equal, indicating something that is unique or unmatched.
Think of something that is 'not' ('un-') 'side by side' ('parallel') with anything else — that's why unparalleled means it has no equal.
