Capitalization Grammar Skill

Capitalization is the use of capital letters at the beginning of words to show importance, proper names, or the start of sentences. Correct capitalization helps writing look clear and professional.

For example, the first word of a sentence is always capitalized, and proper nouns such as names, cities, and holidays begin with capital letters.

Capitalization rules are taught early in writing instruction and continue to develop as students learn how to capitalize titles, places, and specific words correctly.

This skills hub explains common capitalization rules, provides examples, and includes a short quiz to help students practice using capital letters correctly.

Examples of Capitalization in Sentences

Seeing capitalization used correctly helps students understand when capital letters are required. Below are common examples of capitalization rules in action.

  • Beginning of a sentence: The class started early.
  • Proper nouns: We visited New York last summer.
  • Names: My teacher is Mrs. Garcia.
  • Days and months: School starts on Monday in August.
  • Titles: I read Charlotte’s Web last week.

Each example shows how capitalization helps readers identify important words and ideas.
