'purposefully-built' originates from the English word 'purposeful,' which comes from the word 'purpose,' meaning 'the reason for which something is done or created.'

'purposeful' evolved from the Middle English word 'purpos,' which was derived from the Old French 'purpos,' and eventually became the modern English word 'purpose.'

Initially, 'purposeful' meant 'full of purpose,' and over time it evolved to mean 'having a clear intention or aim.'
