A Facebook friend questioned “so” as a sentence starter. So I left this comment:
This isn’t a tic. “So” at the start of a sentence is usually a conjunction meaning “therefore.” It’s perfectly okay to start a sentence with a conjunction. And “so” as a conjunction is more concise than “therefore,” plus it doesn’t require a following comma, which makes the sentence flow more easily. So those who have a problem with “so” beginning a sentence need to explain themselves grammatically or linguistically.
Me, I’m thinking that starting a sentence with “so” instead of “therefore” is like starting a sentence with “but” instead of “however.” Not only okay, but often an improvement. What do you think?

So let it be written. So let it be done.

Excellent, Wm.—“so” as an adverb starting a sentence.

You and your Facebook friend are both right. Starting a sentence with So is perfectly correct, but lately its use has become so prevalent as to take on the characteristics of a verbal tic. Writers who are So fans need to be careful not to overuse it.

Norman: Thanks for commenting. Certainly anything can be overdone. I haven’t seen this one overdone in writing, but it’s probably prone to being overdone in speaking.
