'vigorously-made' originates from the word 'vigorous,' which comes from Latin, specifically the word 'vigor,' where 'vigor' meant 'liveliness or energy.'

'vigor' transformed into the Old French word 'vigour,' and eventually became the modern English word 'vigorous' through Middle English.

Initially, it meant 'full of life or energy,' and over time it evolved into its current meaning of 'done with great energy or enthusiasm.'
