Nouns - Example

A noun is a word used to name a person, animal, place, thing, and abstract idea. Nouns are usually the first words which small children learn. The highlighted words in the following sentences are all nouns:

Last year our neighbours bought a goat.

Justin Bieber is a singer.

The bus inspector looked at all the passengers' passes.

The dog bites the little boy.

These are the examples. Can you differentiate between common nouns and proper nouns?
