"Embiggen"—in the context in which it is used in the episode—is a verb that was coined independently by Dan Greaney in 1996. The literal meaning is "to make something larger", with the morphology (' + ' + ) being parallel to that of ' (' + ""). The verb had in fact previously occurred in an 1884 edition of the British journal "Notes and Queries: A Medium of Intercommunication for Literary Men, General Readers, Etc." by C. A. Ward, in the sentence "but the people magnified them, to make great or "embiggen", if we may invent an English parallel as ugly. After all, use is nearly everything." The word has made its way to common use and was included in Mark Peters' "Yada, Yada, Do'h!, 111 Television Words That Made the Leap From the Screen to Society". In 2018, it was included in the Merriam-Webster dictionary and the online Oxford English Dictionary. In particular, "embiggen" can be found in string theory. The first occurrence of the word was in the journal "High Energy Physics" in the article "Gauge/gravity duality and meta-stable dynamical supersymmetry breaking", which was published on January 23, 2007. For example, the article says: "For large P, the three-form fluxes are dilute, and the gradient of the Myers potential encouraging an anti-D3 to embiggen is very mild." Later this usage was noted in the journal "Nature", which explained that in this context, it means "to grow or expand".
