What this suffix does
-natured forms compound adjectives that describe the innate, fundamental character or disposition of a person — not just how they behave, but what they fundamentally are. Good-natured, ill-natured, sweet-natured, kind-natured — each compound suggests a deep, stable personality trait rather than a temporary mood. The suffix appears in literary descriptions and psychological characterization, often suggesting that the quality is natural and inherent rather than cultivated.
