Separate Elements into Lists

  • Usage: Use commas to separate items in a list.
  • Details: When listing three or more items, insert a comma between each item, except before the last item, where you must use “and” or “or”. Some grammars accept the use of the serial comma (also known as the Oxford comma) before the final “e”.

Before Conjunctions in Coordinated Sentences

  • Usage: Insert a comma before conjunctions (and, but, or, however, yet) when they link two independent clauses.
  • Details: This rule applies when each side of the conjunction functions as a complete sentence and can stand alone.
  • Example: He wanted to leave early, but his friend arrived late.

Isolate Explanatory or Additional Expressions

  • Example: We therefore need to reconsider our strategy.

In Addresses and Dates

  • Usage: Use commas to separate elements in addresses and dates.
  • Details: In dates, separate the day of the month and the year. In addresses, separate the address components and include a comma before the state or country when appropriate.

  • Example: In the summer, I go to the beach; in winter, to the mountain.
