So Tell Me—When Is It Correct to Use So
So: It’s among the shortest words in English, and use of it abounds. So, when are we going to meet up? That movie was so good. I so much want to be there. He’s not feeling well, so he probably won’t go to the meeting.
The word has become a versatile agent for our language during the last couple of centuries. Yet as many of us know, sometimes familiarity can breed contempt. Once a word starts to appear anytime, anywhere, we begin to question its identity and perhaps its validity too.
We all may have heard instances when, similar to the word like, so has served as a sentence filler. This casual use paves the way for so to seep into contexts where it doesn’t belong or may not be needed.
To get to the bottom of what the word really means and how we should approach it in formal writing today, let’s start with how Merriam-Webster online helps to define it:
so (adv): in a manner stated or suggested; in the same way; to a great degree; without a doubt
so (conj): for that reason, therefore; with the result that, in order that
so (adj): agreeing with actual facts, true; marked by a desired order
so (pron): such has been specified or suggested; also used in the phrase or so to indicate an estimate, approximation, or conjecture (It will cost about $500 or so.)
Using those definitions, let’s look at some sentence examples:
so (adv): That outfit makes her look so grown up.
so (conj): The event was longer than we expected, so we decided to leave early.
so (adj): You might think the company is changing its policy, but that isn’t so.
so (pron): If you have to return the item, do so in the next 30 days.
M-W further points out that while some college handbooks renounce so as an “intensive” for comparison (refer to the adverb example above), it still remains standard usage (e.g., Janice was so intelligent that her teachers didn’t know what level to place her in).
Another question concerns whether to use so or so that in clauses that communicate purpose (e.g., Sally stayed home [so or so that] I could go to the ball game). Both the Harbrace College Handbook and The Rinehart Guide to Grammar and Usage agree that so that provides a clearer sentence structure and a better tone for formal writing.
Uncertainty may also arise about how to link clauses including so as a conjunction, as in the following examples:
Pete is the fastest runner; so he’ll run the last leg of the 400-meter relay.
Pete is the fastest runner, so he’ll run the last leg of the 400-meter relay.
Pete is the fastest runner, and so he’ll run the last leg of the 400-meter relay.
Some grammar sources cite the first example above containing the two clauses separated by a semicolon as acceptable; GrammarBook views this style as outdated. Others prefer the second usage, two clauses separated by a comma and so as a conjunction; we agree. A majority would forgo the use of and so with a comma as an unnecessary doubling of conjunctions.
On a similar note, grammar sources concur that writers should not rely on so as an adverb to join ideas that would be better connected with a subordinate clause (one that cannot stand alone in a sentence). Conjoining ideas with so should mainly give them equal emphasis.
Examples
Awkwardly reliant on so: The speakers were friendly, so they got along with everyone, and they were well received.
Better: Because the speakers were friendly, they got along with everyone and were well received.
Equal emphasis with so as an adverb for conjunction: The job required too much travel, so I turned it down.
Putting these thoughts and guidelines into practice should help us rein in runaway so‘s in formal writing, so let’s commit to doing so, shall we?

On TV, I’ve observed, many use “so” when they start answering questions, journalists included.
As you’ve observed, the word so can be used as sentence filler (see the third paragraph of the article) in both written and spoken contexts. Similar to the words well, uh, like (used by the younger generation), and other words, these fillers give the mind a little time to think.
Thank you for providing this information about punctuation rules and words, but I have a question. What happens when I use the word so at the beginning of a sentence (when it refers to the word ¨thus¨ or ¨then¨). For example: ¨We find many sections in the newspapers: political section, gossip section, judicial section, etc, and we read the gossip section a lot because that’s where we find information. So, we always read that part.¨
Is it correct to put a comma after so? I think, here, this word replaces a ¨thereby¨ or ¨thus¨ or ¨then.¨ Thank you so much in advance!
The word “so” here is, in essence, serving as a conjunction meaning “with the result that.”
Punctuating “so” to start the sentence would be a chosen application of informal use similar to how we might inflect when speaking the words in casual conversation. However, if our aim is to be precise with writing, we would not include the comma.
I learned to speak English at the age of ten. I was taught that when you speak or write about having fun, you say, “it was such fun” or “It was so much fun.” Is it correct to say, “It was so fun”? Whenever I hear someone say “so fun,” I want to correct people because it really sounds incorrect to me.
The use of “fun” as an adjective as in “It was so fun” is considered informal. It might be acceptable in casual conversation; however, we would not recommend using it in formal writing.
Use of “so” as a filler beginning spoken and even written sentences has become so annoying.
Excellent examples. I always learn something from your emails. Thank you.
