In linguistics, a sentence is a grammatically complete expression that typically includes a subject and a predicate. It conveys a statement, question, command, or exclamation. Sentences can vary in length and complexity, and they play a crucial role in communication by conveying information and expressing ideas. A sentence must have at least one independent clause, which contains a subject and a verb and can stand alone as a complete thought. It can also have dependent clauses, which cannot stand alone and are typically introduced by subordinating conjunctions. Sentences can be categorized into different types based on their structure and function. These include: 1. Declarative sentences: These make statements or express facts or opinions. Example: "I am going to the store." 2. Interrogative sentences: These ask questions. Example: "Do you like ice cream?" 3. Imperative sentences: These give commands or make requests.
