Plurals/Possessives of Compound Nouns
Explanation |
Form most plurals of compound nouns by pluralizing basic part of/word: attorneys general; vice presidents. "Most dictionaries will give variant spellings of compound plurals," says Professor Charles Darling. "When you have more than one truck filled with sand, do you have several truckfuls or trucksful? The dictionary will give you both, with the first spelling usually preferred. (And the same is true of teaspoonfuls, cupfuls, etc.) The dictionary will help you discover that only one spelling is acceptable for some compounds — like passersby." Professor Darling then says, "For hyphenated forms, the pluralizing -s is usually attached to the element that is actually being pluralized: daughters-in-law, half-moons, mayors-elect." |
---|

Conjunctions
Explanation | Conjunctions join words, phrases, and clauses. Coordinating conjunctions include and, but, for, nor, either, neither, yet, so, so that. Subordinating conjunctions join two clauses (main and dependent/subordinate), and include although, because, since, until, while, etc. |

Business Email Tip
Tip | Keep your message as brief as possible. This is common courtesy. Use short, single-spaced paragraphs. Big, bulky paragraphs are very difficult to read, especially online. No need to indent each paragraph, but do use an extra line between paragraphs. Treat your readers as if they were royalty. |

FREE REIGN OR FREE REIN?
Explanation | It's "rein." Merriam-Webster's says it's unrestricted liberty of action or decision." The Cambridge Dictionary of Idioms says "free rein" is synonymous with "allow" and "give." If you give people, ideas, or a horse free rein, they are free to develop without the intrusion of controlling elements. |
---|

It's or Its?
Explanation | It's means It is or It has. It's time to go. The possessive form (unlike so many words) is NEVER written with an apostrophe: "Its title is" - "What is its value?" |
---|

Wrong or wrongful
Explanation |
The two terms aren't interchangeable. "Wrong" (a noun) means "immoral" or "unlawful," and also means "improper, incorrect, unsatisfactory." So you say, "It's wrong to tell a lie," or "The girl's answer was wrong."
"Wrongful" (an adjective) can mean "unjust," or "unfair," or "unsanctioned by law, having no legal right." So you say "That was wrongful conduct," or "She made wrongful demands of the school." |

When two subjects are joined with "AND"
Explanation | If a subject with two or more parts is joined by "and," is it a compound? Almost always, says Diana Hacker, in A Writer's Reference (G1-c). However, there are exceptions. When the parts of the subject form a single unit (His natural ability and his desire to serve his country have led to a career in the military.) or when they refer to the same person or thing, treat the subject as singular. |
---|---|
Examples, tips | In precise usage, "acronym" refers only to terms based on the initial letters of their various elements, and read as single words (AIDS, NATO); "initialism" refers to terms read as a series of letters (BBC, ATM); and "abbreviation" is used for both acronyms and initialisms. |

"A" or "An" preceding abbreviation
Explanation | When an abbreviation follows an indefinite article, the choice of "a" or "an" is determined by the way the abbreviation would be read aloud, says Chicago Manual of Style (15.9). Acronyms are read as words, it says, except when used as adjectives, and are rarely preceded by "a," "an," or "the." Initialisms are read as a series of letters and are often preceded by an article. |

using ellipsis Marks ...
Explanation | Ellipsis marks (...) are three spaced periods, with one space before and after each period. As a general rule, says Gregg's Reference Manual, don't use ellipsis marks in place of a period at the end of a sentence, but they may be used to indicate that a sentence trails off before the end. Ellipsis marks are often used in advertising to display individual items (similar to bulleting) or to connect a series of loosely related phrases. |

using "a" or "an" before acronyms and initialisms and before certain sounds
Explanation | When an abbreviation (this includes acronyms and
initialisms) follows an indefinite article (like "a" or "an"), the choice is made by the way the abbreviation would sound if spoken aloud. Acronyms (words like NATO, radar, or snafu that are formed from the initial letter or letters of each of the successive or major parts of a compound term) are spoken and read as words unless used adjectivally, like "a HUD program." They're rarely preced by "a," "an," or "the." Initialisms are generally spoken and read as a series of letters and are often (but not always) preceded by an article, e.g., a NATO member, an HTML document, an MS symptom. Use "a" before any word beginning with a consonant sound (a usual response). Use "an" before any word beginning with a vowel sound (an office) (an honorary degree). An initialism (whose letters are sounded out individually, like BBC and USA) may be paired with one article, while an acronym (which is pronounced as a word) beginning with the same letter is paired with the other (an HTML document describing a HUD program). The indefinite article "a" (not "an") is used in American English before words beginning with a pronounced "h." Examples: a hotel, a history lesson, a hopeful sign. Before an abbreviation, symbol, or numeral, one uses "a" or "an" depending on how the term is pronounced. |
---|---|
Examples | an MS treatment (a treatment for multiple sclerosis) ...a MS in the library (MS also stands for manuscript) ...an NBC anchor ...a CBS anchor ...a URL ...an 800 number ...an @ sign |

when not to use the word "lady"
Explanation | According to The Chicago Manual of Style, 15th edition, it's best to use the word "lady" or its plural only in conjunction with the word "gentlemen." Why? It's considered by many to be patronizing to say "lady" as a synonym for "woman." CMS says that some will insist on using it to describe a refined woman, but if they've read the CMS caveat, they've been forewarned. |
---|

On behalf/in behalf
Explanation | "in behalf" means in the interest of or for the benefit of, while "on behalf" means you're acting as an agent or representative of something. |
---|---|
Examples |
In: The decision is in behalf of the patient. On: On behalf of Mr. Scott, I would like to express heartfelt thanks. |

Punctuation: exclamation point
Explanation | Where to place the quotation marks if there is an exclamation point in the quotation instead of a period? Colons, semicolons, question marks and exclamation points all follow closing quotation marks UNLESS a question mark or exclamation point belongs within the quoted matter. CMS gives this example: |
---|---|
Examples | "Where are you from?" The race starts when someone yells, "Go!" |

"A" or "an" before "h"
Explanation | Q. Why is "an historical" said, rather than "a historical"? A. For quite a few years, many journalists said "an historical," and it caught on. But it is not accepted by the major style guides, including Associated Press Stylebook 2003. As "A Writer's Reference" (Hacker) says, "If the h is silent, the word begins with a vowel sound, so use 'an': an hour, an heir, an honest senator, an honorable deed. If the h is pronounced, the word begins with a consonant sound, so use 'a': a hospital, a hymn, a historian, a hotel." |

years, year's or years'
Explanation | For plural nouns ending in -s, add only an apostrophe. |
---|---|
Examples | It gives "six days' vacation" as an example. Go with ...nine years'... |

good×well
Explanation | "good" is an adjective and "well" is an adverb |
---|---|
Examples | Professor Brians says that you do something well, but you give someone something good. The exception he notes, is verbs of sensation in phrases such as "the pie smells good," or "I feel
good." Some people think you should never say "I feel good", but Brians says "Despite the arguments of nigglers, this is standard usage. Saying 'the pie smells well' would imply that the pastry in question had a nose. Similarly, 'I feel well' is also acceptable, especially when discussing health;but it is not the only correct usage." |

i.e. (id est.) & e.g. (exempli gratia)
Explanation | You use i.e. when you mean "that is." You also use it when you're restating the idea (to be more explicit) or expanding upon it. You use e.g. when you mean "for example." In American English, one generally follows i.e. and e.g. with a comma. |
