Proper nouns are specific names for people, places, or things, and they always start with a capital letter. Common nouns are general names for people, places, or things, and they usually start with a lowercase letter. Understanding this difference is important for correct English writing. For example, “teacher” is a common noun, but “Mr. Smith” is a proper noun. Similarly, “city” is a common noun, but “London” is a proper noun. Always remember to use a capital letter for proper nouns to make your English clear and correct.

常见问题
What is the main difference between a proper noun and a common noun?
The main difference is specificity. A proper noun is a specific name (like “London”), and a common noun is a general name (like “city”). Proper nouns always use a capital letter.
Do I always capitalize proper nouns?
Yes, you must always capitalize proper nouns in English, no matter where they appear in a sentence. This includes names of people, places, days, months, and specific organizations.
What about the first word of a sentence?
Always capitalize the first word of any sentence, even if it is a common noun. 例如，, “Dogs are friendly animals.” Here, “Dogs” starts with a capital letter because it is the first word of the sentence, even though “dog” is a common noun.
