'purposefully-designed' originates from the combination of 'purposefully' and 'designed', where 'purposefully' is derived from 'purpose' meaning 'intention' and 'designed' from 'design' meaning 'to plan'.

'purposefully' evolved from the Old French word 'purpos', and 'designed' from the Latin word 'designare'.

Initially, 'purposefully-designed' meant 'created with a specific intention', and this meaning has largely remained the same in modern usage.
