How might the number of languages a person speaks affect their sense of identity?

I'd say speaking multiple languages can deeply shape someone's identity, because it connects them to different cultures and ways of thinking. For example, my friend Lisa, who speaks Mandarin, English, and French, often says she feels like she has different "modes" depending on the language she's using. When she speaks French, she feels more expressive and open, while in English, she's more direct and analytical. That said, it's not always straightforward-sometimes it can create a sense of displacement, especially if someone doesn't feel fully rooted in any one culture. I've noticed this with some bilingual colleagues in Shanghai, who sometimes struggle to find where they truly belong. So while it enriches identity, it can also bring a bit of complexity.
