'oddly-constructed' originates from the combination of 'oddly,' meaning 'in a strange or unusual way,' and 'constructed,' meaning 'built or formed.'

'oddly' comes from the Old Norse word 'oddi,' meaning 'point or angle,' and 'constructed' is derived from the Latin 'constructus,' meaning 'to build or arrange.'

Initially, 'oddly' meant 'in an uneven or peculiar manner,' and 'constructed' meant 'built.' Together, they evolved to describe something built in an unusual way.
