'officially-organized' originates from the combination of 'officially' and 'organized', where 'officially' is derived from 'official', meaning 'authorized or recognized by an authority', and 'organized' from 'organize', meaning 'to arrange systematically'.

'officially' changed from the Old French word 'official', and 'organized' from the Medieval Latin 'organizare', eventually becoming the modern English word 'officially-organized'.

Initially, 'officially' meant 'by authority', and 'organized' meant 'arranged', but over time it evolved into its current meaning of 'arranged in a formal manner'.
