The correct usage of commas in academic writing is a crucial punctuation rule in English grammar. It helps clarify sentence structure and conveys different meanings. Whether signaling a result, cause, or emphasis, mastering this comma usage is essential for effective communication and writing clarity. This article will shed a light on the rules and examples of how to use a comma after “so”.
When to place a comma after “so”
Normally, there is no need for a comma after “so”, or even before it. Just like other conjunctions, it is immediately followed by the clause it introduces. As a meaningless interjection (common in everyday speech) you can, but you don’t have to put a comma before or after “so”. It depends on whether there’s a natural pause at that point in the sentence. Enclosed you will find explanatory examples:
Comma
“So” in introductory clauses
“So” as a pause for emphasis
No comma
“So” in cause-effect-relationship
“So” as an adverb of degree
However, if you’re still not sure which one to use, try to replace “so” with either “therefore” or “so that” and see which one better fits your meaning. Different style guides may present varying rules about comma usage, and certain complex sentences might deviate from conventional comma placement guidelines. It’s essential to assess the necessity of a comma to ensure the clarity and completeness of your sentence.
Comma after “so”
When “so” functions as a parenthical element or coordinating conjunction connecting two independent clauses and is used to mean “therefore” or “for that reason”, a comma is always needed.
“So” in introductory clauses
A comma is typically placed after “so” in introductory clauses. When “so” is used at the beginning of a sentence to introduce an adverbial clause, it’s common to place a comma after it.
Examples
- So, after a long day at work, I decided to treat myself with a nice dinner.
- So, if you’re interested in joining the team, please fill out an application form online.
- So, as it turns out, the solution to the problem was easier than we thought.
When “so” can be replaced with the term “therefore” or “as a result”, you should use a comma before “so”.
“So” as a pause for emphasis
A comma can be used after “so” to create a pause for emphasis or to set off a particular word or phrase. This is often used in everyday speech, depending on whether there’s a natural pause at this point of the sentence, or not. Below you’ll find examples:
Examples
- I can’t believe you did that, so, we’re going to have a serious talk later.
- She said she’d finish the project today, so, we’re expecting to see results.
- He promised he’d be here on time, so, if he’s late again, there will be consequences.
No comma after “so”
When you use “so” instead of “so that” or “in order that”, it’s called a subordinating conjunction. It connects an independent clause with a dependent clause. In everyday speech it is often used as a meaningless interjection where a comma can, but doesn’t necessarily have to be placed, depending on whether there is a natural pause in the sentence or not. However, there’s normally no need or specific rule for a comma after “so”.
“So” in a cause-effect-relationship
When “so” is used in a short sentence to express a clear cause-effect-relationship, a comma is not necessary.
Examples
- She practiced every day so she could become a better dancer.
- John studied hard so he could pass the final exam.
- They saved money so they could afford a nice vacation in Europe.
Examples
- I was so tired that I couldn’t stay awake.
- The lecture was so long and boring!
- She ran so quickly that he won the race easily.
