'unevenly-supplied' originates from the combination of 'unevenly' and 'supplied', where 'unevenly' means 'not level or smooth' and 'supplied' means 'provided or furnished'.

'Unevenly-supplied' combines the adverb 'unevenly' with the past participle 'supplied', forming a compound adjective.

Initially, it meant 'provided in an irregular manner', and this meaning has largely remained the same in modern usage.
