Plug, meaning ‘stopper for a hole,’ dates back to the early 17th century. It was originally a term used by seamen, and came into English from the Dutch plug, which can be traced back to the Middle Dutch plugg and the Old Dutch pluggi, but its origin before then is uncertain. Most linguists agree that the origin is most likely Germanic because most of the related terms are North Germanic and Scandinavian. Some have even suggested the Proto-Germanic plugjaz, though there is not enough evidence to be certain of what the term would have looked like. Plug is related to the Norwegian plugg, Danish pløg, North Frisian plaak, Middle Low German pluck (all meaning ‘plug’), and the German Pflock (plug or peg), and probably related to the Lithuanian plúkti (to strike or hew). The Gaelic plug and the Irish breiseán both derived from the English word. The colloquial sense ‘a piece of chewing tobacco dates back to the early 18th century, and is based on physical resemblance. The electrical sense dates back to the late 19th century, as does the ‘sparking device in an internal combustion engine’ meaning. The advertising sense was first used in US English in the early 20th century, and possibly came from the verbal sense ‘to work tirelessly at something.’ The verb, meaning ‘to close tightly or fill a hole,’ also dates back to the early 17th century. It may have come from the noun, or it may have come into English from the Dutch verb pluggen. The sense ‘to work tirelessly at something’ dates back to the late 19th century, while the advertising sense, like the noun, was first used in the early 20th century.
