More on the topic:

The definite article is the word the. It limits the meaning of a noun to one particular thing.

For example, your friend might ask, “Are you going to the party this weekend?” The definite article tells you that your friend is referring to a specific party that both of you know about.

The definite article can be used with singular, plural, or uncountable nouns.
