English Sentence Structure: Rules for Using "That" in Sentence Construction

As a editor, knowing the proper rules for English sentence construction is essential for creating clear and concise content that is easily understandable by readers. One important aspect of sentence structure to master is the use of the word "that". "That" is often used in English sentences as a conjunction, relative pronoun, or demonstrative pronoun, and its placement can affect the meaning of a sentence. In this article, we will explore the various rules for using "that" in English sentence construction.

Using "That" as a Conjunction

One common usage of "that" in English sentences is as a conjunction, which connects two clauses or phrases. In this case, "that" is often optional and can be omitted without changing the meaning of the sentence. For example:

"I know that he is coming to the party."

"I know he is coming to the party."

In both sentences, "that" is used as a conjunction to connect two clauses. However, the second sentence omits "that" and is still grammatically correct.

Using "That" as a Relative Pronoun

"That" can also be used as a relative pronoun to introduce a subordinate clause that describes or provides information about a noun in the independent clause. In this case, "that" cannot be omitted and is necessary for the sentence's meaning. For example:

"The book that I am reading is very interesting."

In this sentence, "that" serves as a relative pronoun and introduces the subordinate clause "that I am reading". Without "that", the sentence would be incomplete and unclear.

Using "That" as a Demonstrative Pronoun

"That" can also be used as a demonstrative pronoun to refer to a specific noun or object. In this case, "that" is often used to replace the noun or object in subsequent sentences for clarity. For example:

"I saw that movie last night. That movie was very entertaining."

In this case, "that" serves as a demonstrative pronoun and refers to the specific movie mentioned in the first sentence. Using "that" in the second sentence clarifies the subject being referred to and makes the sentence easier to understand.

Summary

The proper use of "that" in English sentence construction is important for creating clear and understandable content. "That" can be used as a conjunction, relative pronoun, or demonstrative pronoun, and its placement can affect the meaning of a sentence. By mastering the rules for using "that" in English sentences, editors can create professional and effective content that engages and informs readers.
