She gave an unblinking answer to the difficult question.
Unblinking → It is formed from "un-" (meaning not) and "blinking" (from Old English "blincan", meaning to close the eyes briefly). The word "unblinking" means not closing the eyes briefly, often used to describe a steady gaze or unwavering attention.
Think of someone who is 'not' ('un-') closing their eyes briefly ('blinking') — that's why unblinking describes a steady, unwavering look.
