Chapter 1-2-10: Countable Nouns
A countable noun (or count noun) is a noun with both a singular and a plural form, and it names anything (or anyone) that you can count. You can make a countable noun plural and attach it to a plural verb in a sentence. Countable nouns are the opposite of non-countable nouns and collective nouns.
People learning English as a second language often have trouble knowing when and when not to use articles. Often, this is because the learner does not know whether the noun was countable (and whether the countable known is plural or singular) or uncountable. It is important to know count versus non-count nouns.
The following table summarize nicely when, and which, articles to use with countable nouns:
