'correctly-structured' originates from the combination of 'correctly' and 'structured', where 'correctly' means 'in a correct manner' and 'structured' means 'arranged in a definite pattern'.

'Correctly' and 'structured' have been used separately in English since the 15th century, and their combination into 'correctly-structured' is a modern usage to describe something organized accurately.

Initially, 'correctly' meant 'in a correct manner', and 'structured' meant 'arranged in a definite pattern'. The combination retains these meanings to describe something organized accurately.
