'publicly-organized' originates from the combination of 'publicly' and 'organized', where 'publicly' is derived from 'public', meaning 'of the people', and 'organized' from 'organize', meaning 'to arrange systematically'.

'publicly' changed from the Old French word 'publique' and 'organized' from the Medieval Latin 'organizare', eventually forming the modern English term 'publicly-organized'.

Initially, 'publicly' meant 'in a public manner' and 'organized' meant 'arranged', and together they have retained the meaning of 'arranged by a public entity'.
