'neatly-organized' originates from the combination of 'neatly' and 'organized', where 'neatly' comes from the Old English 'nēat' meaning 'tidy' and 'organized' from the Greek 'organon' meaning 'tool or instrument'.

'neatly' evolved from Middle English 'net' and 'organized' from Latin 'organizare', eventually forming the modern English compound 'neatly-organized'.

Initially, 'neatly' meant 'tidy' and 'organized' meant 'arranged systematically', and this meaning has largely remained the same in modern usage.
