'traditionally-planned' originates from the combination of 'traditionally' and 'planned', where 'traditionally' comes from 'tradition', meaning 'customs or beliefs passed down', and 'planned' from 'plan', meaning 'a detailed proposal for doing or achieving something'.

'Traditionally' evolved from the Latin word 'traditionem', and 'planned' from the Old French 'plan', eventually forming the modern English term 'traditionally-planned'.

Initially, it meant 'organized according to customs', and this meaning has largely remained the same in modern usage.
