Proper English is important. The only problem with that statement is the definition of “proper.” Language has many levels of formality, all of which are “proper” at times and completely unsuitable at others. Many gradations of formality exist, but to make things easier, divide English into three large categories: “friendspeak” (the most casual), “conversational” (one step up), and “formal” (the equivalent of wearing your best business attire).

When you’re listening or reading, you probably note the difference between formal and informal language constantly — maybe unconsciously. Knowing levels of language, however, isn’t enough. You also need to decide what level of formality to employ when you’re speaking and writing. Before you choose, consider these factors: Your audience.

Three little letters — not — turn a positive comment (“I like your boots”) to a negative one (“I do not like your boots”). Apart from the fashion critique, what do you notice about the negative statement? The verb changes from like to do like. You need that extra part because “I not like” isn’t proper English.

In addition to has, have, had, and the be verbs (am, is, are, was, were, and so on), you can attach a few other helpers to a main verb, and in doing so, change the meaning of the sentence slightly. Consider hiring the following helpers: Should and must add a sense of duty. Notice the sense of obligation in these two sentences: “David should put the ice cream away before he eats the whole thing.

In many languages, you say the equivalent of “Ate the cookie?” to find out whether your friend gobbled up a treat. In English, you nearly always need a helping verb and a subject (the person or thing you’re talking about) to create a question: “Did you eat the cookie?” (The verbs to be and to have are the only exceptions.

English grammar is not a mystery; it's a set of traditions and patterns of language handed down through the ages. With a little practice, you can learn the rules of Standard English so you can express yourself confidently and correctly.Baring the bones of a sentenceWhen you’re writing or checking what you’ve already written, you should pay attention to the “bones” of your sentence — the structure that supports your message.

After you get a good grip on the different parts of speech, it’s time to put them all together to form the proper sentence. The right words and punctuation in the right order can make all the difference in good communication. Keep in mind that you need a minimum number of parts to make a complete sentence: subject/predicate/endmark.
