'sloppily-organized' originates from the combination of 'sloppily' and 'organized', where 'sloppily' is derived from 'sloppy', meaning 'careless', and 'organized' from 'organize', meaning 'to arrange'.

'Sloppy' evolved from the Middle English 'slop', meaning 'loose, baggy', and 'organize' from the Latin 'organizare', meaning 'to arrange'.

Initially, 'sloppy' meant 'loose or baggy', but over time it evolved to mean 'careless', and 'organized' has largely retained its meaning of 'arranged'.
