In linguistic, there is a theory about women and men’s language. Both of those theory explain about how women and men speak. That is why in this research I want to implement whether those theories are true or not. James Charles and Billie Eilish are both amazing and talented celebrities that has shaken the world. Both of their charisma is what led people to be attracted by them. The usage of their language is also different from what we normally think. James Charles can be seen as more feminine and uses women’s language. On the other hand, Billie Eilish can be seen as a more tomboyish girl that sometimes uses swear words. Why is this so? The purpose of this research is to find out the reason why both of them doesn’t apply the linguistic features of women and men’s language. The answer to this question lies on their background.
