To waver is to move unsteadily back and forth — a candle flame wavering in a draught — and then, by extension, to be unsure, to nearly change your mind. So unwavering means holding perfectly steady: not moving, not weakening, not doubting. It is used for things that could easily wobble but don't. Unwavering support, unwavering loyalty, unwavering belief, an unwavering gaze, an unwavering voice.

It has a physical use too, and learners often forget this one: an unwavering stare or an unwavering hand simply means it did not shake. A surgeon's unwavering hands.
