Hello Fellow Writers!
Today’s topic: the dreaded comma. I’m beginning with this as my first post because I find, as a teacher anyway, that commas seem to mystify many. Writers tend to either have comma-phobia (don’t know if there’s a real term) and avoid them almost completely—or they have a serious romantic relationship with commas, and put them, everywhere, there’s a possibility, they might, be able to go. (FYI: grammar check doesn’t think that sentence has any errors…)
Frankly, I don’t think teachers really discuss the purpose of punctuation—including the comma. We don’t use punctuation when we speak, but when we write, we can’t use inflections, pauses, emphases, drama. We’re stuck with what written language can do, thus the need for punctuation. Punctuation is our friend, there to help our text make sense and be clear.
And the comma? It has one use: to separate for clarity. That’s it. Find a sentence with a comma anywhere (well, anywhere that’s using it correctly) and you’ll see it do its work.
And there are only four kinds of texts that need separation: items in a list, complete sentences joined with a conjunction, “conventions” like city and state or name and title, and “what you can take out” (introductory phrases and appositives).
Yep, that’s it. Just four. Some examples may help make this more clear.
