Nouns: countable and uncountable

We could define nouns as words that we use to identify people, objects, concepts and ideas from the world around us. In the English language we can classify them as follows:

Nouns Accountants - (Countable Nouns): Those that can "count", ie it is possible to set the number in units.

Uncountable nouns - (Uncountable Nouns): They are called this way those nouns that can not be determined in units number.

In the case of uncountable nouns can not form the plural, because it is not possible to say "meal", "milk", etc..
