10 Rules for Writing Numbers and Numerals

by Michael

How do you express numbers in your writing? When do you use figures (digits) and when do you write out the number in words (letters)? That is, when do you write 9 and when do you write nine?

1. Number versus numeral. First things first, what is the difference between a number and a numeral? A number is an abstract concept while a numeral is a symbol used to express that number. “Three,” “3″ and “III” are all symbols used to express the same number (or the concept of “threeness”). One could say that the difference between a number and its numerals is like the difference between a person and her name.

2. Spell small numbers out. The small numbers, such as whole numbers smaller than ten, should be spelled out. That’s one rule you can count on. If you don’t spell numbers out it will look like you’re sending an instant message, and you want to be more formal than that in your writing.

3. No other standard rule: Experts don’t always agree on other rules. Some experts say that any one-word number should be written out. Two-word numbers should be expressed in figures. That is, they say you should write outtwelve or twenty. But not 24.

4. Using the comma. In English, the comma is used as a thousands separator (and the period as a decimal separator), to make large numbers easier to read. So write the size of Alaska as 571,951 square miles instead of 571951 square miles. In Continental Europe the opposite is true, periods are used to separate large numbers and the comma is used for decimals. Finally, the International Systems of Units (SI) recommends that a space should be used to separate groups of three digits, and both the comma and the period should be used only to denote decimals, like $13 200,50 (the comma part is a mess… I know).

5. Don’t start a sentence with a numeral. Make it “Fourscore and seven years ago,” not “4 score and 7 years ago.” That means you might have to rewrite some sentences: “Fans bought 400,000 copies the first day” instead of “400,000 copies were sold the first day.”

6. Centuries and decades should be spelled out. Use the Eighties ornineteenth century.

7. Percentages and recipes. With everyday writing and recipes you can use digits, like “4% of the children” or “Add 2 cups of brown rice.” In formal writing, however, you should spell the percentage out like “12 percent of the players” (or “twelve percent of the players,” depending on your preference as explained in point three).

8. If the number is rounded or estimated, spell it out. Rounded numbers over a million are written as a numeral plus a word. Use “About 400 million people speak Spanish natively,” instead of “About 400,000,000 people speak Spanish natively.” If you’re using the exact number, you’d write it out, of course.

9. Two numbers next to each other. It can be confusing if you write “7 13-year-olds”, so write one of them as a numeral, like “seven 13-year-olds”. Pick the number that has the fewest letters.

10. Ordinal numbers and consistency. Don’t say “He was my 1st true love,” but rather “He was my first true love.” Be consistent within the same sentence. If my teacher has 23 beginning students, she also has 18 advanced students, not eighteen advanced students.

Taken from daily writing tip: http://www.dailywritingtips.com/take-care-with-dysphemisms/

You probably know what a euphemism is: putting lipstick on a pig, as in using the expression “pass away” in place of the worddie, or “enhanced interrogation” instead of torture. Is dysphemism — essentially, the opposite concept — any more problematic?

Just as a euphemism cloaks a disagreeable or offensive concept with an innocuous or vague label, dysphemism assigns a mildly or scathingly pejorative term to a concept or person that may be considered neutral or positive or may already have a negative connotation or reputation.

For example, doctors are sometimes called quacks, and psychiatrists and psychologists are often referred to as shrinks. (Quack derives fromquacksalver, from a Dutch word meaning “seller of salves,” or ointments; quackis equivalent to hawk, a verb meaning “to sell by calling out.” Shrink is a truncation of “head shrinker,” from the idea that mental health professionals are no more knowledgeable about the mind than witch doctors who shrink human heads for ritualistic purposes.) Shrink is often used inoffensively, even by psychiatric patients or by psychiatrists themselves. But quack denotes an unscrupulous doctor or someone posing as a doctor or otherwise fraudulently offering to heal others and is rarely used jocularly.

Because of the variable connotations among dysphemisms, writers should take care when considering whether to use them. Such terms are unlikely to appear in formal writing, but they may show up in more casual prose, especially in opinionated comments. An accountant might, in jest, refer to himself as a bean counter, but the connotation is of an excessively meticulous person unable to focus on anything other than saving money, and the term is generally offensive. An attorney, on the other hand, would never call herself a shyster, even in a moment of levity, and the word is provocative.

“City slicker”? I’m a relative newcomer to a rural area from a metropolitan one, and I might jokingly self-identify as such, but for anyone else who might think of calling me that, as the (mis)quote from a Gary Cooper movie goes, “Mister, smile when you call me that.” The same policy applies to tree-hugger orredneck, bookworm or “frat boy,” “pencil pusher” or “talking head”: Use with caution.
