The word "plug" originated in the early 17th century, likely from Middle Dutch plugge ("stopper, peg"), related to German Pflock ("peg"). It originally referred to a stopper for a hole, later extending to electrical devices (19th century) and promotional slang (20th century). Its compact structure reflects Germanic roots, making further morpheme division impractical.
