'regularly-structured' originates from the combination of 'regularly' and 'structured', where 'regularly' comes from Latin 'regularis' meaning 'consistent' and 'structured' from Latin 'structura' meaning 'arrangement'.

'regularly' changed from the Latin word 'regularis' and 'structured' from 'structura', eventually forming the modern English term 'regularly-structured'.

Initially, 'regularly' meant 'consistent' and 'structured' meant 'arrangement', and together they evolved to mean 'having a consistent and organized pattern'.
