IPA: /ʌnˈblʌʃɪŋli/
KK: /ʌnˈblʌʃɪŋli/
In a way that shows no shame or embarrassment; boldly and openly.
She unblushingly admitted her mistake in front of everyone.
Unblushingly → It is formed from "un-" (meaning not) and "blushing" (from Old English "bluscan", meaning to redden or become red). The suffix "-ly" (meaning in a manner) indicates the manner of the action. Therefore, "unblushingly" means to act in a manner that is not red or embarrassed, essentially without shame.
Think of 'not' ('un-') feeling 'red' ('blushing') when doing something — that's why unblushingly means to do something without feeling embarrassed.
