'flour' originates from Old French, specifically the word 'fleur,' where 'fleur' meant 'flower' or 'blossom,' referring to the finest part of the meal.

'fleur' transformed into the Middle English word 'flour,' and eventually became the modern English word 'flour.'

Initially, it meant 'the finest part of the meal,' but over time it evolved into its current meaning of 'powder obtained by grinding grain.'
