'purposefully-changed' originates from the combination of 'purposefully' and 'changed', where 'purposefully' means 'with intention' and 'changed' means 'made different'.

'purposefully' and 'changed' have been used separately in English for centuries, but their combination into 'purposefully-changed' is a modern construct to emphasize intentional alteration.

Initially, 'purposefully' and 'changed' were used separately, but their combination emphasizes a deliberate modification.
