The rules of grammar are many and we will go over some tips as well as tricky rules. Grammar begins at the sentence level. Good sentence structure depends on the words you use. Grammar checkers allow you to check aspects of your grammar. Grammar correction can be easier to put together. While making a diagram of sentences is no longer used as often as a means of teaching grammatical structure, to an extent this can help you learn better. When you diagram a sentence, you begin with an understanding that all sentences have a subject and a predicate. The structure of a sentence determines the way a piece will be put together. One rule of good writing is that the flow of the writing should not be interrupted by sentence structure mistakes such as veering off-topic. Sentences are divided into two types, the simple sentence and the complex sentence. A complex sentence is longer than a simple sentence. Complex sentences also have a subject and a predicate. The subject is made up of the nouns and adjectives while the predicate is made up of verbs, adverbs, or adjectives. A direct object is not a verb but an object such as “Jerry needs a pencil.” When a compound sentence requires a comma, this is called an apposition. The apposition will separate the action described in the sentence. Direct address is another sentence pattern that does not have any direct relation to any part of the sentence. There is always a comma. Grammar in the English language is complex but worth knowing to enhance your writing quality.
