breeding

In a biological context, the word carries a clinical or agricultural tone. It implies a level of intentionality or management—such as in 'selective breeding'—rather than just natural reproduction. When applied to humans (usually as 'good breeding'), the term shifts into a social and class-based register. It suggests an inherited elegance, poise, and adherence to strict social codes. In this sense, it is often associated with old money or aristocracy and can sound archaic or snobbish in modern casual conversation. As a metaphor for cause and effect (e.g., 'breeds contempt'), the word implies a slow, organic growth where one condition naturally nurtures another, often leading to a negative outcome.
