Why is language important in linguistics?

The main function of language is the usefulness of language. It gives us the ability to communicate thoughts, ideas, and feelings with others as quickly as possible. But, within that, we can understand language more by looking at its basic functions.

What do linguists study and why?

They study how to represent the structure of the various aspects of language (such as sounds or meaning), how to account for different linguistic patterns theoretically, and how the different components of language interact with each other. Linguists develop and test scientific hypotheses.
