This poster describes what proper nouns are and when they are capitalized. Proper nouns are specific names used to identify a unique person, place, thing, or idea, differentiating them from common nouns, which refer to general items or concepts. They include names of people (e.g., "Albert Einstein"), geographic locations (e.g., "Mount Everest"), institutions (e.g., "Harvard University"), brand names (e.g., "Nike"), and days of the week or months (e.g., "Friday," "July"). Unlike common nouns, proper nouns are always capitalized regardless of where they appear in a sentence, highlighting their importance. By consistently capitalizing proper nouns, we can easily distinguish them from other types of words, ensuring clarity and precision in communication.
