Why is linguistics a scientific study of language?

正确答案：Linguistics investigates not any particular languagebut languages in general．linguistic study is scientific because it is based on the systematic investigation of authentic language data．No serious linguistic conclusion is reached until after the linguist has done the following three things：observing the way language is actually usedformulating some hypothesesand testing these hypotheses against linguistic facts to prove their validity．During the whole process of his researcha linguist usually follows four principles：exclusivenessconsistencyeconomy and objectivity． 语言学研究的不是某种特殊的语言而是所有的语言。其研究的科学性表现在它是建立在对可靠的语言信息进行系统研究的基础上。语言学家在得出任何严肃的结论之前都要先做以下三件事情：观察语言实际上被使用的方式；形成一些假设；用语言现象证实这些假设的可靠性。在整个研究过程中语言学家通常遵循四条原则：穷尽性、一致性、经济性和客观性。
