Impact.

Impact should remain a noun; a proposal can have an impact, but cannot impact anything without degenerating into jargon. The only thing that can be impacted is a wisdom tooth.

Imperative.

In grammar, an imperative is an order: instead of "You will go" -- the indicative -- the imperative says: "Go." Instead of "You will get the book" -- the indicative -- the imperative says "Get the book."

Though the word imperative is common in business writing, it's big and ugly and intimidating. Go with must or should. Instead of the jargony "It is imperative that the forms be completed on time," try "Be sure to complete the forms on time."

Imply versus Infer.

A speaker implies something by hinting at it; a listener infers something from what he or she hears. Don't use them interchangeably.

Important.

A tip: your thesis statement in an English paper should never contain the word important, which usually means something like "I think this is relevant, but I haven't a clue how." Some examples of bad thesis statements: "The idea of money is important in Defoe's novels," "The role of honor in the epic poems of ancient Greece is very important," or "Race and gender are very important aspects of Toni Morrison's novels" -- they're all very close to meaningless. And don't think a synonym like significant will save you. Say something precise.

Indefinite Articles.

See Articles.

Indicative.

See Subjunctives and Shall versus Will.

Individual.

A yucky word. Usually unnecessary; use person or someone. Use individual only when you mean to distinguish an individual from a group or corporation.

Infinitive.

See Split Infinitive.

Interesting.

Sentences beginning "It is interesting that" or "It is significant that" are usually as far from interesting as can be. Don't just state that something is interesting: show it.

In Terms of.

Often useless padding.

Intransitive Verbs.

See Transitive versus Intransitive Verbs.

Irregardless.

Not a word used in respectable company: somewhere between irrespective and regardless. Use one of these instead.

Italics.

Use italics for book titles, for foreign words, and for emphasis. Be careful, though, not to rely too much on italics for emphasis; they make your writing look amateurish. Let the words do most of the work.

Note that italics and underscores are the same thing -- typewriters used underscore when italics weren't available -- so use one or the other, but not both, in a paper. Publishers prefer underscores in typescripts; they're easier for typesetters to catch. (This is a question of house style.)

See Titles and Fonts.

It's versus Its.

There's no shortcut; all you can do is memorize the rule. It's with an apostrophe means it is; its without an apostrophe means belonging to it. An analogue might provide a mnemonic: think of "he's" ("he is" gets an apostrophe) and "his" ("belonging to him" doesn't).
