The Dash

The dash gives the reader a long pause.

  • The comma (a pause) and the dash (a longer pause) are not used to join main clauses.

  • Main clauses connected with a comma or a dash create a run-on sentence.

The Speaker Clause

A Speaker Clause which is a main or dependent clause comes before or after a quoted statement.

An Exception to the rule:

  • When two main clauses are joined with a comma, a run-on sentence occurs.

  • However, speaker clauses, create a situation which is an exception to that rule.

When a speaker clause comes in front of a quote, it is followed by a comma.


In writing about another kind of Moon Festival celebrated on the Islands, the writer, Joan Clarke, says, "Mid August is also time for the Moon Festival, a Chinese and Vietnamese fete known as Festival of the Reunion."

  • The end quotation mark comes after the period that ends the quote.

When a speaker clause follows a quote, it is preceded by a comma.


"As in the West, the moon also symbolizes romance," says Clarke.

  • The first letter of the first word that follows the quotation is not capitalized.

When a speaker clause comes between main clauses, a run-on sentence is prevented by using a period, a semicolon, or a comma plus a coordinate connective.

  • A run-on sentence occurs before or after the speaker clause - she continues.


Moon cakes are eaten at this time, and "salted duck egg, watermelon seeds, and almonds may be tucked into the center," says Clarke," for it is said that eating moon cakes with seeds will bless one with many children."

  • The comma and the coordinate connective, for have prevented a run-on sentence.
