unyielding
UK: ʌnˈjiːldɪŋ | US: ʌnˈjildɪŋ
adj. not giving way to pressure; firm or stubborn
adj. resistant to persuasion or moral influence
The word "unyielding" combines the prefix "un-" (Old English "un-," meaning "not") with the verb "yield" (Old English "gieldan," meaning "to pay, give, or surrender") and the suffix "-ing" (forming present participles or adjectives). Originally, "yield" referred to yielding in a literal sense (e.g., surrendering or producing), but over time, it evolved to include metaphorical resistance. The addition of "un-" negates this, creating a term that describes steadfastness or refusal to submit.
