A restrictive (synonyms: identifying, defining, essential) clause is used to narrow, limit the reference of the antecedent; to specify a subclass within a broader class of beings or things. It is essential to the meaning of the sentence and cannot be left out. No commas are used to mark off a restrictive clause from the rest of the sentence. | subject | Anyone who wants to leave early may do so. |

A non-restrictive (synonyms: non-identifying, non-defining, non-essential, amplifying) clause gives additional, explanatory information about the object (antecedent) that has been previously specified in the main clause or by context. It can be omitted without changing the essential meaning of the sentence. A non-restrictive clause is set off by commas (sometimes by parentheses or em dashes) from the rest of the sentence. | subject | ||
