What is a noun? It's a naming word. We have two types of nouns: proper and common nouns. Proper noun is a word used to name specific people, things and places. For example: Paul, Bic pen, Addis Ababa. Common nouns name things in general. They are not specific like proper noun. Example include: teacher doctor, chair, table, school, hospital. When marking plural, add s to the end of the noun. For example: Car- cars Cup - Cups. Nouns ending in the letters x, s, or z or in ch or sh sound need es. For example: Boss- bosses Tax - taxes Church - churches.
