The Importance of Commas in Effective Communication

Commas are a crucial part of the English language, used to separate items in a list, set off nonessential clauses, and indicate pauses in speech. However, when it comes to interrupter sentences, the placement of commas can be a bit tricky. In this article, we will explore the correct placement of commas in a sentence that includes an interrupter.

What is an Interrupter Sentence?

An interrupter sentence is a type of sentence that contains an interrupter, which is a word or phrase that interrupts the flow of the sentence. Interrupter sentences often use a comma to separate the interrupter from the rest of the sentence. For example:

"I was going to the store, but I forgot my wallet."
"The two researchers working independently from one another arrived at the same conclusion."

The Correct Placement of Commas in Interrupter Sentences

When it comes to the sentence "The two researchers working independently from one another arrived at the same conclusion," the question is where the commas should be placed. The two possible answers are:

A. After the words "working" and "arrived." B. After the words "from one another."

Option A: Commas After "Working" and "Arrived"

Placing commas after the words "working" and "arrived" would result in the following sentence:

"The two researchers, working independently from one another, arrived at the same conclusion."

However, this placement of commas is incorrect. The interrupter "working independently from one another" is a nonessential clause that provides additional information about the researchers. It is not essential to the meaning of the sentence, and therefore, it should be set off with a comma after the main clause.

Option B: Commas After "From One Another"

Placing commas after the words "from one another" would result in the following sentence:

"The two researchers working independently from one another, arrived at the same conclusion."

This placement of commas is also incorrect. The interrupter "working independently from one another" is a nonessential clause that provides additional information about the researchers. It is not essential to the meaning of the sentence, and therefore, it should be set off with a comma after the main clause.

The Correct Placement of Commas

The correct placement of commas in the sentence "The two researchers working independently from one another arrived at the same conclusion" is after the main clause. The correct sentence would be:

"The two researchers working independently from one another, arrived at the same conclusion."

Why is this the Correct Placement of Commas?

The correct placement of commas is after the main clause because the interrupter "working independently from one another" is a nonessential clause that provides additional information about the researchers. It is not essential to the meaning of the sentence, and therefore, it should be set off with a comma after the main clause.

Conclusion

In conclusion, the correct placement of commas in the sentence "The two researchers working independently from one another arrived at the same conclusion" is after the main clause. This placement of commas is necessary to set off the nonessential clause "working independently from one another" and to provide clarity to the reader.

Common Mistakes to Avoid

When it comes to interrupter sentences, there are several common mistakes to avoid. These include:

Placing commas after the interrupter, rather than after the main clause.
Failing to use commas to set off nonessential clauses.
Using commas to separate items in a list, rather than to indicate pauses in speech.

Use commas to indicate pauses in speech.
Use commas to separate items in a list.
