More on the Word “So”

Margie Wakeman Wells The Comma, The Semicolon 4 Comments

There is a difference of opinion among the “authorities” — Gregg, Morson, CMOS, et cetera — regarding the nature of the word so. Some view it as a coordinate conjunction like and and or. Others view it in the category with therefore and however.

The coordinate conjunctions — and, but, or, nor — do nothing in the language except connect elements that are grammatically equal. That is the definition of a coordinate conjunction. (The word but can be used as a preposition, but this is the only deviation from the basic connecting function.) Since so is an adverb by nature, it would not seem to fit here.

There is another category of conjunction — words that are basically adverbs but can be used as conjunctions. Here is a fairly comprehensive list:

accordingly
also
besides
consequently
furthermore
however
in addition
in fact
indeed
likewise
moreover
nevertheless
otherwise
therefore
hence
plus
so
still
then
thus
yet

These words start out as basic adverbs, answering the questions when, where, how, why. Occasionally, one is pulled out to the front of a sentence and used as a connecting word for that sentence to the sentence in front of it.

…We missed the train; therefore, we had to drive to the location.
…She started to walk toward the street; then her husband came out of the building directly in front of her.

These words are called “conjunctive adverbs.” They join two sentences and show a relationship between them. They are adverbs by nature that are being used as conjunctions.

So fits here. It is an adverb by nature that is occasionally pulled out to the front of the sentence to make a connection to the sentence in front of it. When it does, it means “therefore.”

Conjunctive adverbs take a period or semicolon in front of them and a comma after if they are more than one syllable.

…He raised his hand slightly; so the doctor believed he could hear him.
…I took the train to San Diego; so I was able to get some work done on the way.

Happy punctuating!

  1. Hi, Margie. If the sentence begins “So hence everything is done with your left hand –” would you put commas around “hence” or leave it alone?

  2. Does this mean that every time “so” is in the middle of the sentence, along with the conjunction list, it will take a colon?

    Will the phrase “in terms” fall into this list too? I’ve been getting a lot of sentences with this phrase, and I’m not sure if the same rule applies. I’m not sure how to punctuate this sentence. Thank you, Margie 🙂

      Hi, Rosie.

      When “so” starts a new sentence, it takes a semicolon. When it is in the middle of the sentence, it usually takes nothing.

      …I left so that I could make it to my appointment.
      …She was there so she could learn the new system.

      “In terms of” doesn’t get any special punctuation.

      Have a good day.
