'vigorously' originates from Latin, specifically the word 'vigorosus,' where 'vigor' meant 'liveliness or energy.' 'Constructed' comes from Latin 'constructus,' the past participle of 'construere,' meaning 'to heap together or build.'

'Vigorously' changed from the Old French word 'vigoros' and eventually became the modern English word 'vigorously.' 'Constructed' evolved from the Latin 'constructus' through Middle English 'constructen.'

Initially, 'vigorously' meant 'full of life or energy,' and this meaning has largely remained the same in modern usage. 'Constructed' originally meant 'to build or form,' which is consistent with its current meaning.
