'breeding' originates from Old English, specifically the word 'brēdan,' where 'brēd-' meant 'to produce or bring forth.'

'brēdan' transformed into the Middle English word 'brede,' and eventually became the modern English word 'breed' and its derivative 'breeding.'

Initially, it meant 'to produce or bring forth,' but over time it evolved into its current meanings related to reproduction and upbringing.
