Understanding Relative Clauses

Relative clauses are phrases that provide additional information about a noun. They can be essential (restrictive) or non-essential (non-restrictive). Essential relative clauses are crucial for identifying the noun, while non-essential clauses provide extra information that is not necessary for identification.

Who vs. That: The Basics

Both “who” and “that” can be used to introduce relative clauses, but they are not interchangeable. The choice between “who” and “that” depends on the type of clause and the noun it modifies.

Using “Who”

“Who” is used to refer to people. It can introduce both essential and non-essential relative clauses. Here are some examples:

Essential Clause: The man who lives next door is a doctor.
Non-Essential Clause: My friend, who lives in New York, is coming to visit.

In the first example, the clause "who lives next door" is essential because it identifies which man we are talking about. In the second example, the clause "who lives in New York" is non-essential because it provides extra information about the friend.

Using “That”

“That” can be used to refer to both people and things. It is typically used in essential relative clauses. Here are some examples:

The book that I am reading is very interesting.
The person that won the lottery is my neighbor.

In these examples, the clauses "that I am reading" and "that won the lottery" are essential because they identify which book and which person we are talking about.

When to Use “Who” vs. “That”

The choice between “who” and “that” can be influenced by several factors, including formality, clarity, and style. Here are some guidelines to help you decide:

Formality: In formal writing, "who" is often preferred when referring to people, while "that" is used for things. However, in informal contexts, "that" can be used for both people and things.
Clarity: Use "who" when you want to emphasize the person being referred to. Use "that" when you want to focus on the action or characteristic.
Style: Some writers prefer to use "who" for people and "that" for things to maintain consistency and clarity in their writing.

Common Mistakes to Avoid

There are a few common mistakes that people make when using “who” vs. “that.” Here are some pitfalls to avoid:

Using "that" for people in formal contexts: In formal writing, it is generally better to use "who" when referring to people. For example, instead of saying "The person that won the award," say "The person who won the award."
Using "who" for things: "Who" should only be used to refer to people. Using "who" for things can lead to confusion. For example, instead of saying "The book who I am reading," say "The book that I am reading."
Mixing "who" and "that" in the same sentence: Be consistent in your use of "who" and "that." Mixing them in the same sentence can make your writing unclear. For example, instead of saying "The person who lives next door that is a doctor," say "The person who lives next door is a doctor."

Examples and Exercises

To solidify your understanding of “who” vs. “that,” let’s look at some examples and exercises.

Examples

Here are some examples to illustrate the correct use of “who” and “that”:

The teacher who taught me math is very knowledgeable.
The car that I bought last year is very reliable.
The woman who won the competition is my sister.
The book that I am reading is fascinating.

📝 Note: The answers are: who, that, who, that.

Advanced Usage

In some cases, the choice between “who” and “that” can be influenced by more advanced grammatical rules. Here are a few scenarios to consider:

Using “Whom”

“Whom” is the object form of “who” and is used in formal writing. It is often used in relative clauses where the pronoun is the object of the verb. For example:

The person whom I met at the conference is a renowned scientist.

In this example, "whom" is the object of the verb "met."

Using “Which”

“Which” is used to refer to things, not people. It can introduce both essential and non-essential relative clauses. For example:

The book which I am reading is very interesting.
The car, which is parked outside, belongs to my neighbor.

In the first example, the clause "which I am reading" is essential because it identifies which book we are talking about. In the second example, the clause "which is parked outside" is non-essential because it provides extra information about the car.

Using “Whose”

“Whose” is used to show possession. It can refer to both people and things. For example:

The man whose car was stolen is very upset.
The book whose cover is torn is on the shelf.

In these examples, "whose" shows possession of the car and the book, respectively.
