nerd

Where does the word "nerd" come from? It comes from American English nerd, and was adopted directly into English (1951).

Nerd’s story begins in American English: nerd meant “an imaginary animal.” First printed as a made-up creature in Dr. Seuss's If I Ran the Zoo (1950); its link to the later slang is uncertain. It reached English by 1951 as nerd. Newsweek reported in 1951 that Detroit teenagers called a dull person a 'nerd'; computing culture from the 1980s partly rehabilitated it. Today, nerd means a person seen as overly studious or obsessed with a technical interest.
