Wittgenstein mentions “forms of life” only on a limited number of occasions in his writings; however, this concept is at the core of his approach to language, as the vast literature on the subject shows. My aim in this paper is neither to adjudicate which of the many competing interpretations of “forms of life” is correct nor to propose a new one. I start with a methodological take on this notion and test it by applying it to a specific case. (...) In my view, the notion of forms of life is a methodological tool that Wittgenstein uses to draw attention to the embeddedness of language in our lives and practices. This reading, I suggest, allows us to oppose those who want to see in Wittgenstein a conservative thinker, based on his remark on forms of life as “the given” that must be accepted. In particular, it becomes possible to put his notion to use in the study of linguistic and social change. Hence, I propose as an example the case of innovative language games in trans communities. In this context, the notion of forms of life enables us to see with more clarity how linguistic change occurs, which also helps us better understand phenomena such as disagreement, conflict, and hermeneutical injustice.
