'seldom-manufactured' is a compound word combining 'seldom' and 'manufactured'. 'Seldom' originates from Old English 'seldan', meaning 'rarely', and 'manufactured' comes from Latin 'manu factus', meaning 'made by hand'.

'Seldan' evolved into 'seldom' in Middle English, while 'manu factus' transformed into 'manufacture' through Old French 'manufacture'.

Initially, 'seldom' meant 'rarely' and 'manufactured' meant 'made by hand'. The compound 'seldom-manufactured' retains the original meanings, indicating something rarely made.
