'reduced-fat' originates from the English word 'reduce,' which comes from Latin 'reducere,' meaning 'to bring back.' The term 'fat' is derived from Old English 'fǣtt,' meaning 'plump or well-fed.'

'Reduce' evolved from the Latin 'reducere' through Old French 'reducer,' and 'fat' from Old English 'fǣtt.'

Initially, 'reduce' meant 'to bring back,' but in modern usage, it refers to 'making something smaller or less in amount.'
