What does breeding mean?
Breeding refers primarily to the process by which animals and plants reproduce, particularly when humans deliberately pair them to produce offspring with desirable traits — faster horses, hardier crops, gentler dogs. In agriculture and science, selective breeding underpins much of modern farming, having shaped nearly every domesticated species we rely on. The word carries a second, older meaning as well: a person's breeding denotes their upbringing, manners, and social polish, so that someone 'of good breeding' behaves with refinement presumed to come from a cultivated background. This figurative sense lends the word a formal, sometimes class-conscious flavor in British English especially. The term also appears in the phrase 'a breeding ground', used literally for places where insects or animals multiply and figuratively for environments that foster unrest, crime, or radical ideas. Whether discussing livestock, lineage, or behavior, breeding connects biology and society in a single versatile word.
The process of animals or plants producing offspring, especially under human control to develop desirable characteristics.

Often modified by adjectives such as 'selective', 'cross-', or 'line' in agricultural and scientific contexts.
Good manners and social refinement resulting from careful upbringing; genteel birth or education.

A 'breeding ground' can describe both a hatchery full of mosquitoes and a place where dangerous ideas spread — the same word covers biology and metaphor.

Etymology of breeding
Breeding derives from the verb 'breed', from Old English 'brēdan', meaning to produce offspring or cherish, formed on the Germanic root that also gives us 'brood'. The noun senses developed through Middle English, first covering animal reproduction and later extending to human upbringing and lineage. The figurative sense of refined manners arose from the older notion that one's stock — like that of livestock — determined one's quality.
