What is an error in English?

       The concept of language errors is a fuzzy one. I’ll leave to linguists the technical definitions. Here we’re concerned only with deviations from the standard use of English as judged by sophisticated users such as professional writers, editors, teachers, and literate executives and personnel officers. The aim of this site is to help you avoid low grades, lost employment opportunities, lost business, and titters of amusement at the way you write or speak.

       But isn’t one person’s mistake another’s standard usage?

       Often enough, but if your standard usage causes other people to consider you stupid or ignorant, you may want to consider changing it. You have the right to express yourself in any manner you please, but if you wish to communicate effectively, you should use nonstandard English only when you intend to, rather than fall into it because you don’t know any better.

       Aren’t some of these points awfully picky?

       This is a relative matter. One person’s gaffe is another’s peccadillo. Some common complaints about usage strike me as too persnickety, but I’m just discussing mistakes in English that happen to bother me. Feel free to create your own page listing your own pet peeves, but I welcome suggestions for additions to these pages. First, read the Commonly Made Suggestions page, and if you still want to write me, please do so, after reading the instructions on that page.

       What gives you the right to say what an error in English is?

       I could take the easy way out and say I’m a professor of English and do this sort of thing for a living. True, but my Ph.D. is in comparative literature, not composition or linguistics, and I teach courses in the history of ideas rather than language as such. But I admire good writing and try to encourage it in my students.

       I found a word you criticized in the dictionary!

       You will find certain words or phrases criticized here listed in dictionaries. Note carefully labels like dial. (dialectical), nonstandard, and obsolete before assuming that the dictionary is endorsing them. The primary job of a dictionary is to track how people actually use language. Dictionaries differ among themselves on how much guidance to usage they provide; but the goal of a usage guide like this is substantially different: to protect you against patterns which are regarded by substantial numbers of well-educated people as nonstandard.

       Why do you discuss mainly American usage?

       Because I’m an American, my students are mostly American, and American English is quickly becoming an international standard. I am slowly reworking the site to take note of American deviations from standard British practice. However, the job is complicated by the fact that Canadians, Australians, and many others often follow patterns somewhere between the two. If the standard usage where you are differs from what is described here, tell me about it, and if I think it’s important to do so, I’ll note that fact. Meanwhile, just assume that this site is primarily about American English. If you feel tempted to argue with me, click here first.

       Does it oppress immigrants and subjugated minorities to insist on the use of standard English?

       Language standards can certainly be used for oppressive purposes, but most speakers and writers of all races and classes want to use language in a way that will impress others. The fact is that the world is full of teachers, employers, and other authorities who may penalize you for your nonstandard use of the English language. Feel free to denounce these people if you wish; but if you need their good opinion to get ahead, you'd be wise to learn standard English. Note that I often suggest differing usages as appropriate depending on the setting: spoken vs. written, informal vs. formal; slang is often highly appropriate. In fact, most of the errors discussed on this site are common in the writing of privileged middle-class Americans, and some are characteristic of people with advanced degrees and considerable intellectual attainments. However you come down on this issue, note that the great advantage of an open Web-based educational site like this is that it's voluntary: take what you want and leave the rest. It’s interesting that I have received hundreds of messages from non-native speakers thanking me for these pages and none from such people complaining that my pages discriminate against them.

       But you made a mistake yourself!

       We all do, from time to time. If you think you’ve found an error in my own writing, first read the “Commonly Made Suggestions” page, then follow the instructions on that page if you still think I need correcting. I’ve changed many aspects of these pages in response to such mail; even if I disagree with you, I try to do so politely. If you write me, please don’t call me “Brian.” My given name is Paul.
