English: compound words, continued
Self-tutoring about English: the tutor mentions a peculiarity among compound words.
Back on August 31, 2014, I mention a case of a compound word. A compound word is one that is made of two standalone words brought together. Something is an example.
One peculiarity among compound words is that ones ending with “in” tend to be hyphenated, while ones ending with “out” do not. One case is break-in, but breakout; another is check-in, but checkout.
