Answer:
A common noun is a name of non-specific or a common thing, place or a person. Examples: “ book, pen, room, garden man, girl, road, camera, month, day, chair, school, boy, car” are common nouns because each of them is a common thing, place or person. Common noun refers to a group of items. It does not refer to any specific item.
