The extensive
online database is actually based upon Paul Brians' popular publication,
Common Errors in English Usage. The book is written from the perspective of an American English professor, so the usage concepts contained therein are built upon what is called "standard use" of English. These are the agreed-upon rules that English teachers, professors, literate executives and professional writers all agree constitute proper usage of the English language.
When you arrive at the main page of Paul Brians' website, you'll see a link to "Go to list of errors." When you click on this link, you'll find yourself whisked away to the main page of his database search engine. This is where you can dig through the mountain of English usage examples, which you can then use to improve and enhance your own writing (and speaking) abilities.

The English language is, by its very nature, sometimes a bit backwards and confusing. Often, a single word can have one meaning within one context, and then an entirely different meaning in another. There are similar spellings, figures-of-speech and many other usage concerns that can be difficult for English students to grasp. A website like Paul Brians' list of common errors in English usage serves as a very useful learning tool for those students, and for teachers and professors who teach the English language.
