Grammar: What It Is and Why It Is Important
The mere word strikes terror, or maybe just boredom, into the hearts of English students everywhere. Who wants to spend endless hours learning all of those abstract, difficult (and often illogical or obsolete) concepts that so often seem to have nothing to do with the “real” English we speak every day? I’m pretty sure that as a student I would rather have spent all that time reading, so I sympathize with that attitude. But ultimately it is important and valuable to learn the rules of the language. Essentially, that’s what grammar is: a system of rules governing how we put words together to express ideas. There are more precise terms for certain aspects of linguistic rules, such as usage (conventions about how specific words and expressions are used) and mechanics (rules specific to the written language, such as punctuation and capitalization). Technically, these areas are considered distinct from grammar, but for purposes of organizing the content of this website, all such topics fall into the loose general category of “grammar.” (Katherine Wikoff wrote a detailed discussion of her take on these distinctions that you can read here.)
The question of the value of grammar often comes up with my students. As a true believer, I usually start by acknowledging that the rules of English grammar are often inconsistent, illogical, and outdated. And I admit that I don’t always follow the rules perfectly when I speak or write—nor do I expect them to. But there are compelling reasons for taking the time to learn these things:
1. The rules of grammar help us make our meaning clear to both ourselves and our audience. The sloppier someone’s grammar is, the sloppier their thinking usually is, and the more potential for confusion or misunderstanding exists. Without careful attention to the way you put your words together, expressing complex, nuanced ideas becomes extremely difficult. Conversely, if you’re skilled at putting words together, you can inform, entertain, and inspire.
2. The rules of grammar ensure that we share a common language that everyone who speaks it can understand. As evidenced by the spectacular evolution and fragmentation of languages throughout history, when people don’t have the same clear standard to follow, they end up being completely unable to understand each other.
3. The rules of grammar keep us connected to the rich literary traditions of our language. There is so much to be gained from reading the work of brilliant and thinkers who wrote hundreds of years ago, just as they wrote it. If we don’t learn the rules we’ve inherited, that becomes impossible.
4. The process of learning the rules teaches you to pay close attention to your words. It’s easy to become careless and haphazard in our speech and writing, but practicing these rules forces you to become more aware and more precise. Even if you don’t remember all of the rules you learn, and even if some of them are usually ignored these days, this process makes you a better communicator. The hours I spent learning sentence diagramming in sixth grade and common errors in tenth grade, though often tedious, gave me a great foundation for understanding how to speak and write well. (I was also lucky to have excellent English teachers.)
All of that being said, the rules of grammar aren’t sacred and eternal. Some of the evolutionary changes in language make good sense, and often we want to break the rules for specific rhetorical or stylistic reasons. But when you’ve mastered the rules, you can break them so much more effectively.
Okay, lecture over. I hope you find the information about English grammar that I’ve compiled on this website, and the much vaster resources I’ve linked to, useful. Please feel free to contact me if you have questions regarding any of it.

Grammar and Usage Resources
The list of books and list of online resources below reflects both my twenty years of experience as a tutor and recent research. The resources listed here cover a wide range of grammar topics and are primarily intended for native speakers. See the ESL section of the site for resources appropriate for teachers and students of English As a Second Language.
To find detailed information about the usage of specific expressions, often the most convenient and useful method is a simple Google search for the expression (in quotation marks to limit the search to those exact words), along with a word like idiom to specify that you’re looking for information about its usage (e.g., “out of the frying pan” idiom).
Purdue University’s Online Writing Lab (OWL) is one of the Internet’s most popular resources for students and teachers of English, and for good reason. Under the “General Writing” tab it has extensive resources covering grammar, mechanics, and many other topics. See the separate Exercises page for an excellent set of exercises to go with OWL’s lessons.
The Elements of Style, by William Strunk Jr. and E.B. White, is a classic reference book covering essential points of English grammar, usage, and writing. An early version can be downloaded in various formats from this page on the Project Gutenberg website; a searchable version of the third edition is available on Bartleby here.
The Grammar Girl, Mignon Fogerty, gives practical, easily digestible advice on grammar and writing. Although her website Quick and Dirty Tips covers a broad range of topics unrelated to English, it is a great source of information for students of English.
The websites for the Oxford and Cambridge dictionaries, traditional authorities on the English language, both feature grammar sections. (As an American, I’ll just mention that these are British institutions whose standards sometimes differ from those of American English.)
EnglishClub has a large collection of teaching and learning resources, including exercises, along with a discussion forum. Grammar Monster‘s ad-heavy design isn’t very pleasing, but the site does contain a wealth of useful information and grammar tests on many topics. Grammar.com also contains a lot of free information, though its design is clearly intended to encourage users to purchase its e-books.
For those more interested in getting assistance in correcting grammar errors in their own writing than in studying grammar, Grammarly is a highly rated tool.
Oxford English Grammar is a thorough, detailed reference book that covers even very abstract topics. This has been on my shelf for as long as I’ve been teaching English, and I refer to it whenever I want to understand a topic more deeply or have questions that are difficult to answer.
Oxford Modern English Grammar has the advantages of being more concise and cheaper than the book above, and it’s also available as an e-book. Though it may have some minor flaws, it is an excellent resource for the vast majority of teachers and students.
Michael Swan’s Practical English Usage is another favorite reference tool of mine. It covers every question about grammar and usage that you didn’t know you had—until it randomly comes up when you’re writing something. Note that there is a more expensive version that apparently contains a code for online access to the book’s contents. The third edition is also available as an e-book.
Here are some other books I’m not directly familiar with that seem to be popular and highly regarded:
Cambridge Grammar of English is available in CD-ROM format, which is useful for looking things up quickly.
