'unevenly-associated' originates from the combination of 'unevenly' and 'associated', where 'unevenly' means 'not level or smooth' and 'associated' means 'connected or linked'.

'unevenly' changed from the Old English word 'unefen' meaning 'not even', and 'associated' from the Latin word 'associatus', meaning 'joined with'.

Initially, 'unevenly' meant 'not level', and 'associated' meant 'joined with', but over time, the combination evolved to describe things that are not uniformly connected.
