Learn the difference between countable and uncountable nouns with this English grammar lesson.Countable nouns are separate objects that we can count. They have a singular and a plural form and we can use the indefinite article with them ("a" or "an")Uncountable nouns are things like liquids, materials or a mass of substance with no boundaries. They only have a singular form and we cannot use "a" or "an" before them. We can use the word "some", for example "There is some rice."Some nouns can be both countable and uncountable depending on the context or situation.It is very important to learn if a noun is countable or not because the English grammar rules for both types of nouns are different.If you have any questions abou this or any question about the English language, then please ask in the comments.
