What's the point? Other than the dot at the end of the sentence. Believe it or not, you already know a lot about punctuation. You read it every day and your brain remembers it a little, even if you don't. Trust me on this, I'm a total grammar geek. You know when it looks right and when it doesn't, but you may not always know why it's not right. Perhaps English isn't your first language and you just want to throw the dictionary at someone, preferably an English professor. You can try to hit me with it, but I learned how to duck. Maybe you just want to make things easier for your readers. Whatever your reason for skinny-dipping into my punctuation pool on an erotic site, welcome!
We're going to deal with a few primary pieces of punctuation and one that should be far more rare than it is around here. Each portion of this piece will be headed by the name of the punctuation in bold so you can find it easily without having to muck through a lot of reading that doesn't have anything to do with you.
0. Essential Grammar
You have to know a little grammar to know when to use what punctuation. I'm going to keep the grammar minimal, short, teeny-tiny. That way you don't suffer any more than you have to. Chances are, you already know these things, but you may not know their names. We're basically going to deal with just clauses and phrases.
Clauses are parts of a sentence, not just the things that come back to kick you in the ass after you signed a contract or bought insurance. They don't always prance around with elves (though the one in this sentence does) either. A clause is a group of words that has a subject and a predicate. The subject is what the sentence is about and the predicate is what the sentence does. There are four classifications of clauses, but we won't get into those. What we will get into are the two types of clauses. Yes, there's a difference. Yes, it's probably pretty boring. There are two types of clauses, an independent or main clause and a dependent or subordinate clause.
An independent clause can stand alone all by itself. Here's an example: “The traffic stopped". It has a subject, the traffic, and a predicate, stopped. More importantly it's a complete thought. The idea, notion, whatever is all there.
A dependent clause cannot stand on its own. It has a subject and a predicate, but it's not a stand-alone because the thought isn't complete. Here's an example: “When her skirt blew up". No, really, that's not a complete sentence. Think about it for a minute. If that was all by itself, you'd be wondering what made her skirt blow up and what the writer meant by “when". There's some missing information here. Put them together and you have a complete, compound sentence. The traffic stopped when her skirt blew up.
There are two quick ways to tell a dependent clause from a clause that's wearing the whole sentence bikini. One: look for a “time" or “it depends" word. When, after, sometimes, usually, if, because. Two: look for a gerund. A gerund is just a fancy word for a verb with an -ing whacked at the end. Looking, eating, smelling, seeing, being. All of that fun stuff.
Groups of words that seem to stand alone, but are missing either the subject or the predicate are called phrases. There are tons of these buggers in writing and they come in all shapes and sizes. The best way to recognize one is to look for a subject and a predicate. If one is missing, it's a phrase.
Well that was relatively painless. Or at least I thought so. C'mon, you can uncover your eyes now.
1. The Period: (.)
The period is the most common piece of punctuation you'll ever type. It's at the end of nearly ever sentence (except this one)! It also has a few more uses that might come in handy along the way.
The first thing is how to end a sentence. As you already may know, it goes at the end. Look at these sentences and you'll see the period in action. There is one point and it comes immediately after the letter preceding it. Then there is generally two spaces between the period and the sentence that comes after it. Sometimes there'll only be one space, but conventionally speaking, there are two. You'll notice that the first letter in the sentence following is capitalized. Easy enough. But to be a good Muffie, here are a few examples:
This is a sentence.
There is a period at the end of this sentence, too.
The period also works in with things like abbreviations. This is where it gets slightly trickier. As with the sentence, the period follows immediately after the abbreviation and then a space before the next word in the sentence. That's a single space, not two. Here are a few examples to help you along:
Mrs. Robinson
Dr. Pepper
I live in the U.S.A., but I like the U.K. and U.S.S.R. in the summer.
Note: Acronyms, abbreviations that are pronounced as words, do not have periods. Here's a few examples: modem (Modulater/demodulater), SEAL (SEa, Air and Land), ASAP (as soon as possible). Certain abbreviations, such as RCMP and FBI frequently aren't seen sporting periods, either.
If the abbreviation comes at the end of a sentence, there's a bit of a problem. How many periods? One or two? Just one! The sentence ender is the ender of the abbr. Cool, huh? C'mon work with me here. Here's an example for you:
Jim wanted to be cool, but he's just an S.O.B.
(Sue me, I couldn't think of anything else.)
Ah! Another one of those murky questions, you noticed. Where, exactly, does the period go when you've got things like parentheses in the way? I'll deal with punctuation with quotation marks in that section.
When dealing with parentheses, the punctuation depends on how the parentheses are placed in the sentence. If they're mixed in with the sentence (like this) then you keep all the punctuation outside of the parentheses (even at the end). If you put them around an entire sentence, you put the punctuation inside of the parentheses. (Kind of like this.) Here are a few examples:
My momma told me (you'd better wash your hands).
(I'm not too keen on copyright violations.)
You may have noticed that in some stories, there are strings of periods throughout the text. There really is a punctuation mark that requires more than one period. It's commonly known as the ellipses, which is covered in Section 8. Ellipses.
2. The Comma
This is where things get complicated. Commas are used for so many things and you have to know some grammar. If you haven't already given it a once over, check Section 0. Grammar for a brief run-down of the grammar you'll need to know.
A Dependent Clause Does the Independent Clause in the Conga Line.
Sometimes they do that. What do I mean here? It's not self-explanatory? Great. Now I'm going to confuse everybody. In this case the dependent clause usually modifies the independent clause. That means that whatever the dependent clause is about, changes or explains the independent clause in some way. We call these adverbial dependent clauses, but you don't have to know that for the test.
Remember her skirt? And the traffic? When her skirt blew up, traffic stopped. Yep, that one! Traffic stopped is the independent clause. Yes, I know the other one has more words, but that doesn't matter. Traffic stopped tells you everything you need to know. However, the clause “When her skirt blew up" makes it even better because it tells you why traffic stopped. It wasn't something you needed to know, but it did make things a bunch more interesting. Oh just admit it, we already know you've got a dirty mind. You're here, aren't you?
Here are some examples:
When he ran the stoplight, the nice officer pulled him over.
If we ate lunch, I would still want dessert.
While running around the desk, I thought about letting the boss catch me.
Participial Phrases, Infinitives, and All That Jazz.
The jazz has a better beat, but we still must deal with the other two. We use them all the time, you know. Most of us don't even realize they have names. Probably don't care, either. For the purposes of our discussion, an infinitive is just a phrase that has some form of “to be" involved. There's more to it, but it's not necessary and would probably be really, well, dull.
A participial phrase is just one where a group of words showing action of some sort acts to describe something in the sentence. Like adverbials, these just really describe something about the rest of the sentence. When you use them, though, there should be a comma between the phrase and the clause.
Let's look at a pair of sentences. To have sex, you should probably be horny. Howling like a wolf at the moon, she had an orgasm. With these two sentences, you have a couple of independent clauses. “You should probably be horny" and “she had an orgasm". The first one has an infinitive phrase in the beginning, “to have sex". You'll notice that it's a linking verb, or a form of the verb be. Conjugation isn't just another dirty word! The second one has a participial phrase, “howling like a wolf at the moon". They both sort of describe the rest of the sentence; quite a bit actually, without being strictly necessary to the sentence.
Here are a few examples:
To be truly pretty, she should smile.
To have a cookie, the dog has to sit up and beg first.
