'barn' originates from Old English, specifically the word 'bern,' where 'bere' meant 'barley' and 'ærn' meant 'house.'

'bern' transformed into the Middle English word 'berne,' and eventually became the modern English word 'barn.'

Initially, it meant 'a house for storing barley,' but over time it evolved into its current meaning of 'a building for storing farm products or housing livestock.'
