Grog is traced as follows: Named after 'Old Grog', the nickname of Admiral Edward Vernon, who wore a grogram cloak and in 1740 ordered sailors' rum to be diluted with water; grogram itself is from French gros grain ('coarse grain'). The etymological value lies in the continuity between the older named form and the modern English word, even where no further internal segmentation is supplied. In present use, it is used as a noun meaning "a drink of spirits, especially rum, diluted with water", so the historical material remains connected with the current sense rather than standing as bare ancestry. The wider English family includes derivatives such as groggy and groggery and related forms such as groggery and groggy, showing how the same historical material continues to organize neighboring vocabulary. Its semantic neighborhood includes liquor, spirits, drink, and tipple, locating the modern specialization without adding a new origin story.
