Name the 100 most-spoken world languages by FIRST LANGUAGE SPEAKERS. For all but the first 20, a clue about the language's categorization (often a family or subfamily) is given. I tried to make the clues useful.
From http://www2.harpercollege.edu/mhealy/g101ilec/intro/clt/cltclt/top100.html - I have NOT combined or renamed languages as people typically do
Languages with the same name (for instance, Egyptian and Algerian Arabic) are not grouped but can be guessed with the name of the language (Arabic); Chinese is not considered one language, nor is Hindustani
Language categorizations do not equal countries; not all Iranian languages are spoken in Iran, or Tai languages in Thailand
Let me know of type-in issues - I'm rusty and this was a lot
