👽 What are some common English words of unknown origin?

🤖 Nerd

 A person who is boring, stupid and not fashionable

The word nerd is documented to have been first used in the 1950s in the United States. It first appeared in a 1951 article in Newsweek, which declared ‘In Detroit, someone who once would be called a drip or a square is now, regrettably, a nerd.”

Even before that, nerd was used by Dr. Seuss in his book If I Ran the Zoo (published in 1950) as the name of an imaginary creature. However, it is not known where the word really came from.
