How to Choose the Right Synonym
Choosing an alternative to “that” becomes easier when you first identify what you want the word to do.
For People: Use “Who”
When “that” refers to a person, who is often a natural alternative.
Example:
“The writer that won the award…”
“The writer who won the award…”
In standard English, “who” is generally the clearest choice when referring to people.
For Things: Use “Which”
When referring to a thing and adding extra information, which can be appropriate.
Example:
“She bought a camera, which was very expensive.”
“Which” is especially common when the information is additional rather than essential.
For Places: Use “Where”
When the noun refers to a location, where can often make the sentence more natural.
Example:
“This is the school where I studied.”
This is usually smoother than repeatedly using “that” in location-related sentences.
For Time: Use “When”
When discussing a particular time, when can be useful.
Example:
“I remember the year when we moved.”
It clearly tells the reader that the following information relates to time.
For Formal Writing: Use “In Which,” “By Which,” or “Through Which”
Academic and professional writing sometimes requires more precise relationships.
Examples:
“The environment in which children learn affects their development.”
“The method by which the information was collected was carefully documented.”
“The system through which payments are processed is secure.”
These expressions should be used when they improve precision, not simply to make writing sound complicated.
For Referring Back: Use “This,” “It,” “Such,” or “The Aforementioned”
If you have already introduced an idea, you can often avoid repeating “that.”
Example:
“The company changed its policy. This affected many employees.”
Or:
“The company changed its policy. As a result, many employees had to adapt.”
These choices can make paragraphs flow more naturally.
For Showing a Reason: Use “Because,” “Since,” or “As”
When the intended meaning is a reason, choose a word that clearly expresses cause.
Example:
“Because the train was late, we missed the meeting.”
“Since the train was late, we missed the meeting.”
“As the train was late, we missed the meeting.”
The choice depends partly on tone and sentence structure.
For Showing a Result: Use “Therefore” or “Consequently”
When you want to show a result, transitional words can make the relationship between ideas clearer.
Example:
“The evidence was weak. Therefore, the conclusion was reconsidered.”
These words work particularly well in essays, reports, and professional writing.
Common Mistakes When Replacing “That”
A common mistake is assuming that every synonym can replace “that” in every sentence.
This is not true.
For example:
“I know that she is busy.”
You cannot simply replace “that” with “which”:
“I know which she is busy.”
The meaning and grammar change.
Another common mistake is using formal alternatives when simple English would be better.
For example, “the aforementioned” may be correct in a legal document, but it can sound unnecessarily complicated in a friendly blog post.
Good writing is not about replacing common words with difficult words. It is about choosing the most accurate and natural expression for the situation.
