2. Commas
Commas are used to separate items in a list and to separate clauses within a sentence. They help make the sentence easier to read.
3. Question Marks
Question marks are used to end a sentence that is a question. They signal that the reader is asking for information.
4. Exclamation Points
Exclamation points are used to end a sentence that expresses strong emotion or excitement. They signal that the speaker is very excited or emphatic.
Detailed Explanation
Periods
Periods are used at the end of a sentence to show that the thought is complete. For example, "The cat is sleeping." The period indicates that the sentence is finished and the reader can move on to the next thought.
Commas
Commas are used to separate items in a list, such as "I need apples, bananas, and oranges." They are also used to separate clauses within a sentence, like "She went to the store, but she forgot her wallet." Commas help the reader understand the structure of the sentence.
Question Marks
Question marks are used at the end of a sentence to show that it is a question. For example, "Did you see the movie?" The question mark indicates that the reader is asking for information.
Exclamation Points
Exclamation points are used to show strong emotion or excitement. For example, "What a beautiful day!" The exclamation point indicates that the speaker is very excited or emphatic about the statement.
