PUNCH UP
YOUR
PUNCTUATION
YOUVE BRUSHED UP ON YOUR grammar, you know how to choose the right words, and youve gotten over your writers block by ignoring all the biddies who say you cant start a sentence with however, and, and the like. Now all you need is to string all those words together so they actually make sense. Punctuation helps with that.
Punctuation may seem like extraneous little hacks and splashes on the page, but those marks actually help readers stay on track. Punctuation is a polite gesture toward your reader: Here, dear reader, allow me to guide you through this sentence. Its a long one, and it might be a little confusing, but Ive provided clues and signposts along the way. I promise you wont get lost .
Were going to start out easy with the period and work our way up to the more exotic punctuation marks like ellipses and asterisks. If we make it all the way to the interrobang, I might have to put on an evening gown!
P ERIODICITY
The period is quite a straightforward punctuation mark. I think its safe to say everyone knows that a period ends a sentence. What everyone doesnt know is how many spaces should come after a period and how to deal with periods in acronyms.
Space: The Final Frontier
If you learned to type on a typewriter, you were probably taught that you should leave two spaces after a period at the end of a sentence. The space bar on a typewriter makes a space that is the same size regardless of whether you are at the end of a word or the end of a sentence, which is the reason typewriter fonts are called monospaced fonts. In order to make a strong visual break between sentences on a typewriter, you need to type two spaces.
Now that most writing is done on computers, it is no longer necessary to type two spaces after a period at the end of a sentence. Word processing and typesetting software recognizes periods at the end of sentences, and if you are using a proportional font (which most fonts are these days), font designers have already made sure a properly sized space will be inserted between sentences.
Technically, whether you put one or two spaces after a period is still a matter of style. Some editors still prefer two spaces, but most style guides recommend one space, and page designers have written in begging me to advise people to leave only one space. They have told me that using two spaces can create unappealing rivers of white space throughout a document, and that if you are writing something that layout or design people will ever get their hands on, they will almost certainly have to go through your document and take out the extra space. So I recommend using only one space.
Acro-nymo-batics
No strict rule governs whether you should put periods after each letter in an acronym or initialism. Some publications put periods after each letter, arguing that because each letter is essentially an abbreviation for a word, periods are necessary. Other publications dont put periods after each letter, arguing that the copy looks cleaner without them and that because they are made up of all capital letters, the fact that they are abbreviations is implied.
Abbreviation Information
Any shortened form of a word is an abbreviation, for example, etc. for etcetera and Oct. for October; but acronyms are special kinds of abbreviations, such as ROFL (rolling on the floor laughing) and OPEC (Organization of Petroleum Exporting Countries), that can be pronounced as words. This makes them a subset of abbreviations. All acronyms are abbreviations, but not all abbreviations are acronyms.
Initialisms are another type of abbreviation. They are often confused with acronyms because they are made up of letters, so they look similar, but they cant be pronounced as words. FBI and CIA are examples of initialisms because theyre made up of the first letters of Federal Bureau of Investigation and Central Intelligence Agency, respectively, but they arent usually pronounced as words. (People have written in to tell me that insiders often say fibby for FBI, but its not something Ive ever heard used among the general public.) NASA, on the other hand, is an acronym because even though it is also made up of the first letters of the department name (National Aeronautics and Space Administration), it is pronounced as a word, NASA, and not by spelling out the letters N, A, S, A.
When you have an abbreviation at the end of a sentence, dont use a second period. The period at the end of the abbreviation becomes a super period (not the technical term) that does the task of both shortening the abbreviation and ending the sentence. (If you think losing the clear ending to a sentence will confuse your readers, its best to rewrite the sentence so the abbreviation doesnt come at the end, or write out the full word instead of using the abbreviation.) On the other hand, when you end a question or an exclamation with an abbreviation, you do include both the ending period of the abbreviation and the final question mark or exclamation point.
Squiggly always wanted to work for the F.B.I.
Doesnt Aardvark prefer the C.I.A.?
T HE Q UESTION M ARK : H UH ?
You think you already know how to ask questions, dont you? I wonder if youre right.
Everybody knows how to write a plain vanilla question: whats new? Theyre called direct questions. But there are trickier scenarios. What happens when a sentence seems to be half statement, half question? What if youre asking an indirect question, asking a question that also seems to require an exclamation point, dealing with a quotation that contains a question, and so on?
Questions Masquerading as Statements
Sometimes even direct questions are tricky because they can look like statements, and the only way to tell your reader otherwise is to add a question mark. Theres a big difference in meaning between Squiggly went to the store. and Squiggy went to the store? Yet the only difference between the two sentences is that one ends with a period and one ends with a question mark. The question mark makes it a direct question that shows surprise. What the heck was he doing at the store?
A Question Flurry
What if you have a bunch of questions and you want to string them all together?
I love a scene in the movie Cats & Dogs where a dog realizes he can talk. It goes something like this: You can hear me? Can I have a cookie? two cookies? four cookies? twenty cookies? Those add-on questions at the end arent complete sentences but they each get a question mark anyway. Since they arent complete sentences, you usually dont capitalize the first letter, but the rules are vague. Some guides say to capitalize the first letter if the questions are nearly a sentence or have sentence-like status, so you have to use your own judgment. I dont consider two cookies to be nearly a sentence, but I may consider something like two cookies and a squeaking ball to chase to be nearly a sentence, which would make me consider capitalizing it.
