Groggery comes from grog + -ery. Grog is named after 'Old Grog', Admiral Edward Vernon, who ordered sailors' rum diluted with water; -ery denotes a place of business. Morphologically, the account is both compositional and suffixal: -ery marks the visible structure by which the older base becomes the modern form. In present use, it is used as a noun meaning "a cheap tavern or barroom selling liquor", so the historical material remains connected with the current sense rather than standing as bare ancestry. The wider English family includes related forms such as grog and groggy, showing how the same historical material continues to organize neighboring vocabulary. Its semantic neighborhood includes tavern, saloon, barroom, and dive, locating the modern specialization without adding a new origin story.
