'unevenly-constructed' originates from the combination of 'unevenly' and 'constructed'. 'Unevenly' comes from 'uneven', which originates from Old English 'unefen', where 'un-' meant 'not' and 'efen' meant 'even'. 'Constructed' comes from Latin 'constructus', the past participle of 'construere', where 'con-' meant 'together' and 'struere' meant 'to pile up'.

'Unevenly' changed from the Old English word 'unefen' and eventually became the modern English word 'unevenly'. 'Constructed' evolved from the Latin 'constructus' through Middle English 'constructen'.

Initially, 'unevenly' meant 'not even', and 'constructed' meant 'built'. Over time, 'unevenly-constructed' evolved to describe something built without uniformity.
