What’s included
semicolonThe mark ; used to join two closely related statements that could each stand alone as a sentence. It also separates list items that already contain commas.

You’ll leave with these skills

  1. Avoid a comma that merely separates a subject from its verbFind the subject and its main verb. Their length does not justify a comma between them. A comma before the verb may still be needed to close an added description.
  2. Find the main verb after a subject that holds a “that” or “who” partCover the defining that or who clause to identify the subject and its main verb. Do not insert a comma simply because the subject is long. Check separately whether a comma closes an added description.
  3. Keep a verb with its object and a preposition with its noun phraseDo not separate placed from what was placed, or a preposition such as of or during from the noun phrase following it. Punctuation can still mark an inserted aside, rather than separate those grammatical parts.
  4. Spot a comma that splits describing words from their nounPut no comma between the describing words and the noun they describe.
