'marmalade' originates from Portuguese, specifically the word 'marmelada,' where 'marmelo' meant 'quince.'

'marmelada' transformed into the French word 'marmelade,' and eventually became the modern English word 'marmalade' through Middle English.

Initially, it meant 'a preserve made from quinces,' but over time it evolved into its current meaning of 'a preserve made from citrus fruits.'
