adamant
UK: ˈædəmənt | US: ˈædəmənt
adj. refusing to be persuaded or to change one's mind; unyielding
n. (archaic) a legendary hard substance, often identified with diamond or lodestone
The word "adamant" traces back to Greek adamas (ἀδάμας), meaning "unconquerable" or "untameable," originally used to describe the hardest metal or stone (later associated with diamond). The Latin adamant- preserved this sense of hardness and inflexibility. Over time, the adjective form evolved to describe unyielding attitudes, while the noun form became archaic. The morpheme a- (Greek/Latin negative prefix) reinforces the idea of resistance, while -damant derives from daman (to tame/subdue), highlighting defiance.
