* Period (.) - Used for declarative sentences (statements)
* Question mark (?) - Used for interrogative sentences (questions)
* Exclamation point (!) - Used for exclamatory sentences (expressions of strong emotion)
Here are some additional things to consider:
* Independent Clauses: Sentences can be made up of one or more independent clauses. An independent clause is a group of words that contains a subject and a verb and can stand alone as a complete thought.
* Dependent Clauses: Dependent clauses cannot stand alone as a sentence. They need to be attached to an independent clause.
* Conjunctions: Words like "and," "but," and "or" can connect independent clauses within a sentence.
Example:
* The dog barked loudly. (One independent clause)
* The dog barked loudly, and the cat hissed. (Two independent clauses connected by "and")
* When the dog barked loudly, the cat hissed. (One independent clause and one dependent clause)
Important Note: While the basic rules are straightforward, there are exceptions and complexities in grammar. If you're unsure about sentence structure, it's always best to consult a grammar guide or a professional.
