'neatly-structured' originates from the combination of 'neatly' and 'structured'. 'Neatly' comes from the Old English 'nēat', meaning 'tidy', and 'structured' comes from the Latin 'structura', meaning 'a fitting together'.

'Neatly' evolved from the Old English 'nēat' and 'structured' from the Latin 'structura', eventually forming the modern English compound adjective 'neatly-structured'.

Initially, 'neatly' meant 'tidy' and 'structured' meant 'a fitting together', but over time, they combined to describe something organized in a tidy and systematic way.
