Each type of punctuation has its own rules, but here are a few basics to keep in mind when marking up your paper:

  1. Periods come at the end of sentences.
  2. Leave no space between punctuation and the preceding word (except parentheses and quotation marks).
  3. A single space comes after almost all punctuation. The exceptions are parentheses, quotation marks, and hyphenated words, which all have no space between them and the following word. Also, we don’t use typewriters anymore, so there’s no need for putting two spaces between sentences. Keep it uniform with one.
  4. When writing by hand, don’t make extra marks on the paper. Koreans in particular have a habit of putting a dot after writing a word, almost as though they are gathering their thoughts for the next part of the sentence. This creates a false stop, however, which can make your paper difficult to read.
  5. Shorter sentences help make your work more readable. Use full stops frequently to emphasize points or communicate better with children.
