Quite simply, a singular noun is a noun that refers to only one person, one place, one thing, or one idea. If you look at one object and name it, you have an example of a singular noun. For example there is one lamp on my bookcase and one chair at my desk.
Most nouns have singular and plural forms. A noun with a singular and plural form (e.g., dog/dogs, man/men) is called a countable noun. A countable noun contrasts with a non-countable noun, which does not have a plural form (e.g., music, bravery).
