'truly-changed' originates from the combination of 'truly' and 'changed', where 'truly' means 'in a truthful manner' and 'changed' means 'made different'.

'truly' and 'changed' have been used in English since the Middle Ages, and their combination into 'truly-changed' reflects a modern emphasis on authenticity.

Initially, 'truly' and 'changed' were used separately, but their combination emphasizes a genuine transformation.
