Etymology
It is inherited from Old English bere-ærn (“barley house”) (about 950), contracted to bern,[2][3][4] from bere, barley, and ærn, house, storeroom,[2][3][4] which is metathesized from *rasn, cognate with Old Norse rann, large house, and Gothic razn, house.[3][2][4] The same element is in Old English sealtærn, saltworks, and horsern, stable.[3]
Earliest recorded meaning
A covered building for storing grain: about 950.[5][2]
Semantic evolution
Etymonline notes that barley was the chief grain crop in Anglo-Saxon England.[3] In the United States a barn is also a stable or cattle house (1770),[5] and a large shed for railway cars or buses.[6][7] A large, bare building is called a barn.[6][7] The verb, to store in a barn, is from 1593.[5][8] In nuclear physics, the barn, a unit of area for cross-sections, is from 1947, said to come from the phrase as big as a barn or barn door.[5][9]
