'introverted' originates from Latin, specifically the word 'introvertere,' where 'intro-' meant 'inward' and 'vertere' meant 'to turn.'

'introvertere' transformed into the English word 'introvert,' and eventually became the modern English word 'introverted.'

Initially, it meant 'to turn inward,' but over time it evolved into its current meaning of 'shy and reserved.'
