Common nouns are either count or non-count.
From the point of view of grammar, this means that count nouns have singular as well as plural forms, whereas non-count nouns have only a singular form. In general, non-count nouns are considered to refer to indivisible wholes. For this reason, they are sometimes called MASS nouns. Some common nouns may be either count or non-count, depending on the kind of reference they have. For example, in I made a cake , cake is a count noun, and the a before it indicates singular number.
