IPA: /ˌʌnroʊˈmæn.tɪˌzaɪzd/
KK: /ʌnˈroʊmənˌtaɪzd/
Describing something that is presented in a realistic or straightforward way, without embellishment or idealization.
The documentary offered an unromanticized view of life in the city, showing both its beauty and its struggles.
Unromanticized → It is formed from "un-" (meaning not), "romantic" (from Latin "romanticus", meaning having the qualities of romance), and "-ized" (meaning to make or become). The word means to make something not romantic or to remove romantic qualities from it.
Think of 'not' ('un-') making something 'romantic' less appealing or idealized — that's what unromanticized means.
