'monoecious' originates from Greek, specifically the word 'monoikhos,' where 'monos' meant 'single' and 'oikos' meant 'house.'

'monoecious' changed from the New Latin word 'monoecius' and eventually became the modern English word 'monoecious.'

Initially, it meant 'having one house' (referring to both sexes in one organism), and over time it evolved into its current botanical meaning of 'having both male and female reproductive organs in the same individual.'
