Fivestages,twolinesandthreebreakthroughsarethegeneraltrendofthestudiesoflinguistics.The five stages refer to those of philology, historical/comparative linguistics, structural linguistics, formal linguistics and intersectional linguistics; the two lines stand for those of Regularity and Irregularity that have competed throughout the history of western linguistics; and the three breakthroughs are presented by those of historical/comparative linguistics, Saussurean linguistics, and sociolinguistics, each of which played a crucial role in promoting linguistics studies into a new era. Therefore the general summarization of Five Stages, Two Lines and Three Breakthroughs provides a way that looks back into the history of linguistics studies, which may shed light on further studies in question.
