Unyieldingly → It is formed from "un-" (meaning not) and "yield" (from Old English "gieldan", meaning to give or surrender) and the suffix "-ingly" (meaning in a manner). The word "unyieldingly" means in a manner that does not give way or surrender.
Think of 'not giving way' ('un-') and 'surrendering' ('yield') to remember that 'unyieldingly' describes a firm and resolute manner.
