Unfortunately, some writers assign proper-noun status indiscriminately to words, sprinkling capital letters freely throughout their writing. For example, the Manhattan Project is correctly capitalized because it is a historic project, the name given to the specific wartime effort to design and build the first nuclear weapons. But the common noun project should not be capitalized when referring to a club's project to clean up the campus, for example. Similarly, the Great Depression should be capitalized because it refers to the specific period of economic failure that began with the stock market collapse in 1929. When the word depression refers to other economic hard times, however, it is not a proper noun; it is a common noun and should not be capitalized.
Some flexibility in capitalizing nouns is acceptable. A writer may have a valid reason for capitalizing a particular term. For example, some companies have style guides that dictate capital letters for job titles such as manager. But often the capitalization beyond the basic guidelines is an effort to give a word an air of importance, and you should avoid it.
Gerunds
Sleeping sometimes serves as an escape from studying.
Problem GerundsA word that stands for a group of things is called a collective noun. In fact, the word group itself is a collective noun. Here are a few others: family, club, team, committee, staff, furniture, jury, Congress, audience, herd.Usually these nouns are treated as singular because the emphasis is on the action of the entire unit rather than its individual parts.
The committee wants to find a solution to the problem.
The team have argued about going on the bus.
If the plural sounds awkward, try rewording.
The committee members want different solutions to the problem.
Here are some examples of Latin and Greek singular and plural words that can be troublesome: bacterium, bacteria; criterion, criteria; medium, media; alumnus (masculine singular) , alumni (masculine plural), alumna(feminine singular), alumnae (feminine plural).
Problems with possessivesSometimes possessives can cause problems. Do I add an ’s or just an apostrophe? Follow this rule: For singular nouns, add ’s, even if the noun ends in an ‐s or ‐z sound: dog's, house's, Wes's, Jesus's, Denver's, Keats's.For most plural possessive nouns, add an apostrophe alone: several months' bills, many Romanians' apartments, the encyclopedias' differences. If a plural noun doesn't end in ‐s, add ‐'s, just as you would with a singular noun: women's issues, mice's tails.Switching to an of constructionWhen a possessive noun sounds awkward, reword to use an of construction. This is a better way to indicate the relationship, especially when referring to an inanimate object: the top of the page instead of the page's top; the lawn of the building on the corner instead of the building on the corner's lawn; the main characters of Pride and Prejudice instead of Pride and Prejudice's main characters; the novels of Dickens instead of Dickens's novels.Joint ownershipOne last word about possessive nouns: When you are indicating joint ownership, use the possessive form in the final name only, such as Abbott and Costello's movies; Tom and Dawn's dinner party; Smith, Wilson, and Nelson's partnership.Agreement of Nouns and VerbsAgreement is an important concept in grammar and a source of many writing errors. Nouns must agree with their verbs, which means that a singular noun requires a singular verb, and a plural noun requires a plural verb.The rabbit jumps up and down. (singular) The rabbits jump up and down. (plural)Remember that a noun ending in ‐s is often a plural, whereas a verb ending in ‐s is usually singular: four home runs (plural noun); he runs fast (singular verb). Nouns with Latin or Greek endings and nouns that look plural but sometimes take singular verbs can cause agreement problems.In the following example, criteria is plural. Use the plural form of the verb ( are). The criteria for judging an entry are listed in the brochure.Rights, which is a plural form, is treated as singular in the following example because human rights is a unit, a single issue of concern. Human rights is an issue that affects everyone.To emphasize the rights individually, use the plural verb.Human rights are ignored in many countries.In the next example, miles is the plural form, but fifty miles is used to identify a single unit of distance and therefore takes a singular verb. Fifty miles is not such a long distance.Statistics looks plural, and in many situations is treated as plural. In the first example below, statistics refers to a subject of study, so the singular verb is appropriate. Statistics is a subject I want to avoid.Statistics are being gathered to show that women are better drivers than men.Among other frequently used nouns that can take either a singular or plural verb, depending on whether the emphasis is on a single unit or individual items, are number, majority, and minority.The number of people coming is surprising.A number of people are coming.A number like five thousand is what he had in mind.With number, use this rule. If number is preceded by the, always use the singular verb. If number is preceded by a, use the singular or plural, depending on whether you are describing a single unit or individual items. With majority and minority, the key is to decide whether you want to emphasize individual people or things or the single unit. The majority is opposed to the measure. (singular = single unit)A minority of the younger people refuse to concede the point. (plural = individuals)
