'oddly-parted' originates from the combination of 'oddly,' meaning 'in a strange or unusual way,' and 'parted,' meaning 'divided or separated.'

'Oddly-parted' combines the Middle English 'odde' meaning 'singular' and 'parten' meaning 'to divide.'

Initially, it meant 'strangely divided,' and this meaning has largely remained the same in modern usage.
