'seldom-partitioned' originates from the combination of 'seldom' and 'partitioned'. 'Seldom' comes from Old English 'seldan', meaning 'rarely', and 'partitioned' comes from Latin 'partitio', meaning 'division'.

'Seldan' transformed into the Middle English 'seldom', and 'partitio' evolved into the English 'partitioned', eventually forming the modern English compound 'seldom-partitioned'.

Initially, 'seldom' meant 'rarely', and 'partitioned' meant 'divided'. The compound 'seldom-partitioned' retains the meaning of 'rarely divided'.
