'vibrant' originates from Latin, specifically the word 'vibrāre,' where 'vibrā-' meant 'to move to and fro.'

'vibrāre' transformed into the French word 'vibrant,' and eventually became the modern English word 'vibrant' through Middle English.

Initially, it meant 'to move to and fro,' but over time it evolved into its current meaning of 'full of energy and life.'
