'regularly-positioned' originates from the combination of 'regularly' and 'positioned', where 'regularly' comes from Latin 'regularis', meaning 'consistent', and 'positioned' comes from Latin 'positio', meaning 'placement'.

'regularly' changed from the Latin word 'regularis' and 'positioned' from 'positio', eventually forming the modern English term 'regularly-positioned'.

Initially, 'regularly' meant 'in a consistent manner' and 'positioned' meant 'placed', and this meaning has largely remained the same in modern usage.
