Webster's 10th edition is wrong. The whole is composed of the parts, or the whole comprises the parts. Comprise is to include or contain. Substitute the word include, and if it works, so will comprise. Use composed of, not comprised of.
Do not use the word stomach to denote the abdominal area. Stomach is that organ inside your body. It's very difficult to scratch your stomach. You would scratch your abdomen, or in more informal writing, your belly. We don't have stomach muscles and we don't lie on our stomachs. We lie on our bellies (or abdomens, or facedown), and we have abdominal muscles, or, in more informal writing, ab muscles or abs. Furthermore, abdominal is an adjective, so only use the word to describe a noun: abdominal muscles, abdominal area, but not abdominals.
Don't use apostrophes to denote plural, and don't use them with numbers:
Entitled means to furnish with a right. Titled is the better choice to express the title of a work.
Individual/individuals and person/people mean the same thing. You'll see the word individuals most often in academic text. In academic text, try to vary the usage with person and people. In trade text, avoid using the word individual unless you're distinguishing a single person or people from a group.
Everyday is an adjective meaning ordinary. Every day means each day. We're seeing the word everyday more and more in advertising copy, but most often it's used incorrectly. Here are correct uses:
Never use awhile after a preposition. You can say stay awhile but not stay for awhile.
Something that makes you sick (a rocking ship or the Spice Girls) is nauseous. You are nauseated if you feel as if you'll vomit. A person who feels sick is no more nauseous than a person who has been poisoned is poisonous.
Think of alright the same way you should think of alot. It's still two words, and double the l.
Principle is always a noun; it can't be used as an adjective. Principal is an adjective meaning "main" or "primary" unless it's used to mean the head of a school or a chief person in a function:
Center means to focus or zero in. Therefore, use on with center. If you must use around, use revolve with it. Do not use center around.
Fazed means "affected." Pneumonic device: Remember the f in affected; that will help you to remember the f spelling instead of the ph spelling.
If you feel badly, that means you grope clumsily or incorrectly at something. You feel bad about something. Feel is a linking verb, so a form of to be can substituted for feel and the meaning doesn't change much.
That which is another one of those big fancy constructions that is expressed just as clearly with what. That which is also more British in nature. Try to avoid it.
Try and is common in casual speech, but don't use it in writing. Literally it means one is going to try to do something and then go ahead and do something. Use try to.
Fewer applies to units, less to quantity. Fewer modifies a plural noun (fewer persons, things, ideas), less a singular noun (less joy, anger, money).
Between usually applies to a one-on-one situation and usually connotes a more specific relation than among does.
Except in British English, farther means "more distant," usually in a measurable sense, as in Is Chicago or St. Louis farther from Indianapolis? In an abstract sense, further would be used:
Continual means "constantly recurrent" and continuous means "uninterrupted." Note the following examples:
To compare something with something else is to point out their similarities, differences, or both. To compare something to Something else is simply to assert that they're alike. Think of compare to the same way you think of liken to.
Unless you're describing a tennis ball smashing into a racket, do NOT use "impact" as a verb! Use "affect," "has an effect on," or "has an impact on."
Do not use "while" to mean "although." Authors often use the "while" construction, but it can mislead the reader to think that it's a statement of time.
Do not use "as" to mean "because." Again, it's a temporal word that can be misleading.
These phrases are imperatives (commands), so they should not be followed by question marks.
This is becoming common in newspaper headlines, and I've noticed that authors of our books are following suit. Long noun phrases functioning as adjectives are clumsy, ambiguous, misleading, and not very grammatical. Examples are "resource management challenges" (better as "challenges in resource management") "natural resource protection" (should be "protection of natural resources" because the former makes the phrase sound as if the protection is natural, which isn't accurate), and "skeletal muscle carbohydrate metabolism" (should be "carbohydrate metabolism in skeletal muscle").
