Studying syntax gives us many answers which are necessary for understanding how languages work, as well as being the doorway to future research and theories on all aspects of linguistics!
We also study syntax to develop set rules and constraints on the language. We call these parameters. These parameters limit what we can and can’t do in a language, helping us establish an effective and working communicative system. Some linguists believe that all languages have the same parameters. This idea is called universal grammar, and was a theory developed by Chomsky in the 1960s. From these ideas of linguistic parameters, we can learn, use and teach the correct way to make sentences. Basically, so we can all understand each other!
