'astronomy' originates from Greek, specifically the word 'astronomia,' where 'astro-' meant 'star' and '-nomia' meant 'law or culture.'

'astronomia' transformed into the Latin word 'astronomia,' and eventually became the modern English word 'astronomy' through Old French.

Initially, it meant 'the law of the stars,' but over time it evolved into its current meaning of 'the scientific study of celestial bodies.'
