inclement

The word 'inclement' is a direct borrowing from Latin inclemens, formed by the negative prefix in- attached to clemens, meaning "not mild". The Latin clemens is thought to derive from a Proto-Indo-European root meaning "to lean" or "be inclined", which evolved into a sense of "leaning toward kindness" or "yielding". In English, the term was first applied to describe harsh, unyielding weather, and its use was later extended in a more figurative, archaic sense to describe severe or unmerciful human behavior. The logic of the word perfectly captures the concept of nature or temperament refusing to be gentle.

Structure: in (not) + clement (mild) - in: Latin origin, a prefix meaning "not" or "without". - clement: Latin origin, from clemens meaning "mild, gentle, merciful". It functions as the core root describing a quality of weather or temperament.
