There are three major types of nouns.
Common nouns, as the name suggests, are the largest variety. Common nouns signify a general class of words used in naming and include such words as those in the following list: car, shoe, computer, baby, disk, pad,etc.
Proper nouns, on the other hand, are specific names, such as Mr. smith.
Mass nouns are a special category of common nouns. What makes them distinct is that, unlike simple common nouns, they cannot be counted. Below is a short list of mass nouns: deer, air, mud, research, meat,etc.
