'traditionally-developed' originates from the combination of 'traditionally' and 'developed', where 'traditionally' comes from 'tradition' meaning 'customs or beliefs passed down' and 'developed' from 'develop' meaning 'to grow or cause to grow'.

'traditionally' evolved from the Latin word 'traditionem', and 'developed' from the Old French 'desveloper', eventually forming the modern English term 'traditionally-developed'.

Initially, 'traditionally-developed' referred to methods or processes that evolved over time, and this meaning has largely remained the same in modern usage.
