A sentence is an independent unit of grammar that expresses a complete idea with a subject and a verb. It is a fundamental part of any language and is the largest independent unit in English. Sentences may be declarative, interrogative, imperative or exclamatory. It is also possible for sentences to be complex or compound-complex.
Most paragraphs have a topic sentence that introduces the main idea of the whole section. Then each paragraph should develop that idea with supporting details and examples. Finally, the paragraph should draw some kind of conclusion or sum up. If you write in a structured way, your paragraphs will be easier to read and your readers will find it more interesting.
Sentence structure is the arrangement of sentences and clauses in a coherent manner. Sentences should have a clear subject and a verb and all the words in a sentence should agree with each other. Consistency in point of view, verb tense and number is important for coherence. If you use the personal pronoun “you” in one sentence and the impersonal pronoun “one” in another, or if you shift between past and present tense, or from singular to plural, it will make your writing less consistent and difficult for your reader to follow.
A word or group of words that describe the subject of a sentence is called a predicate. The word or phrase that makes sense on its own is the subject of a sentence. The rest of the words that cannot stand on their own are subordinate clauses. For example, She has a diamond ring and lives in Dubai is the subject of a sentence.
