'Rosaceae' originates from Latin, specifically the word 'rosaceus,' where 'rosa' meant 'rose' and the suffix '-aceus' meant 'of or pertaining to.'

'Rosaceae' was formed in New Latin as a scientific family name based on the type genus 'Rosa' and the standard botanical suffix '-aceae,' and eventually became the modern English term for the rose family.

Initially, it meant 'the family of plants related to roses,' and this meaning has remained consistent in modern usage, referring to the botanical family including roses and related plants.
