Origin Story
Sailors in the eighteenth-century Royal Navy received a daily ration of rum. It was strong, and drunkenness during working hours was common. In August 1740, Admiral Edward Vernon, commanding the West Indies squadron, ordered that the rum be issued diluted with water — a measure meant to preserve discipline and reduce accidents. The sailors called him "Old Grog," reportedly because he favored a cloak made of grogram, a coarse fabric whose name comes from the French gros grain, "coarse grain." The watered rum accordingly took the name grog, and the unsteadiness it produced came to be called groggy. Both words appear in the English record from around 1770.
One point calls for caution. The account that Vernon was nicknamed "Old Grog" for his grogram cloak is widely accepted, but the sources reporting it postdate the events by several decades, and etymological dictionaries hedge it with the word "reputed." Meanwhile, groggy was used frequently in nineteenth-century boxing, where it shed its specifically alcoholic sense and broadened into today's meaning of a body that will not quite obey.
