A sentence is an array of words arranged in a particular order that conveys a fact, a question, a statement, an order or an exclamation. It must be complete and express a clear idea. It must also contain a subject and a predicate.
Sentences have a specific word order and the subject with or without the determiner comes first. Then the verb follows the subject. Then the complement or adverbial phrase, and if necessary, a direct object follows. For example, The Taj Mahal is magnificent and Mr. Anoop Jalota is a bhajan singer.
It is important to understand the different types of sentences, and the way in which they are constructed. This will help you avoid run-on sentences, and allow you to fully develop your ideas and arguments.
It is also important to be consistent in your use of key words or phrases. This helps your readers to keep track of the ideas you are presenting. Avoid using the same words or phrases over and over again, however. This type of repetition can stall the development of your ideas, and it is often difficult for the reader to follow. Instead, try to create parallel structures, or chains of sentences that have the same grammatical structure and use the same parts of speech. For example, in a paragraph on scientists and sight, the first sentence might explain how scientists can see things by using their sense of sight. Then the second sentence might explain how their eyes work, and the third sentence might describe the way in which their brains process information from their eyes.
