Contrary to popular perception, “Abdul” is not a word or name in Arabic. In Arabic, “Abdul” is completely nonsensical.
How did I know that?  It was covered in the Call of Cthulhu game book that I have.  Lovecraft didn't really know what he was doing when he made up the name "Abdul Alhazred."  But then he was only a kid at the time.

Read the whole thing, if you find languages interesting.  And there is a combination of word names that can come out sounding like "Abdul" to our western ears.

Yes, you can learn things by playing games.  When I got into playing Aces of the Pacific, I learned more about World War II than I had ever been taught in school.
