Lots of words in the English language are or were two words originally.

  • Somehow
  • Nobody
  • Erstwhile

But many often conjoined words are not 'allowed'. The one that springs to mind is 'alot'.

Why are some of these ok, and others not? How do these joined-up words enter English vocabulary but not others?
