Punctuation

Punctuation marks help readers follow the structure and meaning of written messages. They can show where a sentence ends, whether a direct question is being asked, or how parts of a sentence fit together. These examples describe ordinary English writing.

Three Ending Marks

A period, also called a full stop, often ends a statement or a calm request: “We can play.” A question mark ends a direct question: “Can we play?” An exclamation point, also called an exclamation mark, can show strong feeling: “We won!” An exclamation does not always mean shouting.

The same words can carry different emphasis. “We won.” can report a result calmly, while “We won!” can show excitement. Choose a mark that fits the message you intend. A mark is not a letter or a whole word.

Commas Have Jobs

A comma can separate items in a list or show who is being addressed. In “Let's help, Sam,” the speaker asks Sam to join in helping. In “Let's help Sam,” Sam is the person to help. The comma changes how the words fit together.

Reading aloud may include pauses, but a pause alone is not a rule for inserting a comma. Think about the sentence's structure and meaning.

Capitals and Endings Work Together

In ordinary English sentence writing, the first word begins with a capital. A suitable ending mark helps show where that sentence finishes. The English word I is uppercase even inside a sentence: “You and I can go.” A capital letter and an ending mark have different jobs.

Try It

Point to the marks in “I can hop.”, “Can I hop?” and “I did it!” Name each one. Then write or dictate a little message, telling your grown-up which letters and mark you choose.

Make and edit your own messages.
