Linguists are the professionals who are dedicated to the study of languages, particularly as regards their origin, evolution and structure. It is they, for example, who make dictionaries, grammars and other materials concerning oral or written language. For this reason, we can conclude that the linguist studies languages, just as the archaeologist studies artifacts.
Linguists are also dedicated to the study of factors that influence language. For example, sociolinguistics seeks to explain the interference of social factors on the language plane, while psycholinguistics investigates how our perception of reality determines language and how it conditions our view of the world.
