barn

A barn is an outbuilding on a farm used to keep animals or crops safe and dry. A farmer might store hay in the upper part of a barn, and have stalls for horses in the main section.

In rural areas there are many barns, often built from wood and standing near a main farmhouse. Some barns have wide doors with stalls for animals inside, and a hayloft at the top, where hay or other crops can be stored. In Old English, a barn or bereærn literally meant "barley house," from bere, "barley," and aern, "house."
