'rigorously-organized' originates from the combination of 'rigorous' and 'organized', where 'rigorous' comes from Latin 'rigor', meaning 'stiffness', and 'organized' from Greek 'organon', meaning 'tool' or 'instrument'.

'rigorous' changed from the Latin word 'rigor' and 'organized' from the Greek 'organon', eventually becoming the modern English phrase 'rigorously-organized'.

Initially, 'rigorous' meant 'stiffness', but over time it evolved into its current meaning of 'strict precision', while 'organized' retained its meaning of 'arranged systematically'.
