Emily Dickinson Lexicon

DAI'RY, n. [This word I have not found in any other language. In Russ. doyu signifies to milk, and Junius mentions dey, an old word for milk, and Icelandic deggia, to milk. It may be, and probably is, a contracted word.]

1. Milk, and all that concerns it, on a farm; or the business of managing milk, and of making butter and cheese. The whole establishment respecting milk, in a family, or on a farm. Grounds were turned much in England either to feeding or dairy; and this advanced the trade of English butter. Temple.
2. The place, room or house, where milk is set for cream, managed, and converted into butter or cheese. Dryden.
3. Milk-farm. Bacon.
