Who/Which Clause (w/w)

Short Version:

When do you use “who”? – When talking about people. 

When do you use “which”? – When talking about things. 

How do I indicate a who/which clause? 

Underline and bold only the who or which, not the whole clause. 

Remember! A who/which clause cannot stand alone as a complete sentence. The complete sentence must have 2 parts to it! The w/w is part of sentence

Clause: A group of words that has both a subject and a verb. 

A “who or which” clause is simply a group of words that begins with who or which and has a verb in it. (The who or which is the subject of the clause.) 

When do you use “who”? – When talking about people. 

When do you use “which”? – When talking about things. 

What about animals? If they act like humans or are pets, use “who.” If they are clearly animals, use “which.” 

To indicate the who/which clause: Underline and bold only the who or which, not the whole clause. If you have more than one, indicate only one in every paragraph or as stipulated in the assignment. 

Two ways to form: 

1. Take two sentences that begin with the same subject and turn one into a “who” or “which” clause.

 Examples: 

The yellow-bellied sapsucker is native to Canada and the northern United States. It destroys young trees by sucking sap from the branches. 

The yellow-bellied sapsucker, which is native to Canada and the northern United States, destroys young trees by sucking sap from the branches. 

John Smith knew how to trade with the Indians for food. He helped save Jamestown. 

John Smith, who knew how to trade with the Indians for food, helped save Jamestown.

2. Take a noun (person or thing) and add information to it in the form of a “who” or “which” clause. 

Examples: 

The lion was most grateful for the appearance of the little mouse. 

The lion, who felt he would never be able to disentangle himself from the hunter’s net, was most grateful for the appearance of the little mouse. 

John Smith made a clever rule. 

John Smith, who helped to save Jamestown, made a clever rule. 

CRUCIAL: Don’t let your “who” or “which” try to be a sentence by itself! 

The disheveled princess stood dripping. 

The disheveled princess, who stood dripping. (What’s wrong with this?) 

A who/which clause cannot stand alone as a complete sentence. 

The “who/which” clause is one of several kinds of dependent clauses. This one is an adjective clause because the entire clause describes a noun and therefore follows a noun. 

Grammar Rule #10: 

The who/which clause is usually set off by commas. If you take it out of the sentence, you should still have a sentence left. To check: If you remove the who or which clause, do you still have a sentence that can stand alone and make sense? 

The disheveled young woman, who stood at the door with water dripping down her back and into her shoes, claimed Princess Authenticity. 

If we remove the highlighted “who” clause, it is still a complete sentence: The disheveled young woman claimed Princess Authenticity.
