As a language expert with a deep understanding of English grammar and punctuation, I can provide you with a comprehensive answer to your question about the placement of commas with the conjunction "but."
The use of commas in conjunction with the word "but" can be a bit tricky, as it depends on the context in which "but" is used. "But" is a coordinating conjunction, which is used to connect two independent clauses. When "but" is used in this way, it is generally not followed by a comma if the clauses are short and closely related. However, if the clauses are long or if there is a need to emphasize the contrast between them, a comma can be used after "but" for clarity and readability.

Here are some rules and guidelines to consider when deciding whether to use a comma before or after "but":

1. **Use a comma after "but" when connecting two independent clauses**: If "but" is connecting two independent clauses (clauses that can stand alone as sentences), a comma is typically used after "but". This is because the comma helps to separate the two clauses and makes the sentence easier to read.

Example: "I wanted to go to the party, but I had too much homework to do."

2. **No comma is needed if the clauses are short and closely related**: If the two clauses connected by "but" are short and closely related, a comma may not be necessary. The flow of the sentence can naturally convey the contrast without the need for a comma.

Example: "She was tired but determined to finish the race."

3. **Use a comma for emphasis or to clarify a complex sentence**: In some cases, a comma after "but" can be used for emphasis or to clarify a complex sentence. This is especially true if the sentence could be confusing without the comma.

Example: "I didn't go to the store, but my sister did."

4. **Consider the tone and rhythm of your writing**: The decision to use a comma can also be influenced by the tone and rhythm of your writing. A comma can create a pause, which can be used to create a dramatic effect or to give the reader time to absorb the contrast.

Example: "The cake was delicious, but it was also very rich."


5. Consistency is key: Whatever rule you choose to follow, be consistent throughout your writing. Inconsistency in the use of commas can make your writing appear unprofessional or confusing.


6. Follow the style guide for your context: Different style guides (such as APA, MLA, or Chicago) may have specific rules about comma usage. It's important to follow the guide that is relevant to your context, whether it's academic writing, professional communication, or creative writing.

In conclusion, while there are general guidelines for using commas with "but," the ultimate decision should be based on the context, the relationship between the clauses, and the desired effect on the reader. The reference content you provided suggests that it is rare to follow a coordinating conjunction with a comma, which aligns with the general rule that a comma is typically not used after "but" when connecting two independent clauses. However, there are exceptions, and the decision to use a comma should be made with careful consideration of the factors mentioned above.

We cannot say that the comma will always come before the conjunction and never after, but it would be a rare event, indeed, that we need to follow a coordinating conjunction with a comma. When speaking, we do sometimes pause after the little conjunction, but there is seldom a good reason to put a comma there.read more >>
