'evenly-grown' originates from the combination of 'evenly' and 'grown', where 'evenly' means 'in equal or uniform measure' and 'grown' is the past participle of 'grow', meaning 'to increase in size or develop'.

'Evenly-grown' combines the adverb 'evenly' from Old English 'efenlice' and the past participle 'grown' from Old English 'grōwan'.

Initially, 'evenly-grown' meant 'grown in a balanced manner', and this meaning has remained consistent in modern usage.
