What Jacques derrida mean by other and otherness?

Jacques Derrida's concepts of "other" and "otherness" revolve around the idea of difference and the complexity of identity. He challenges the notion of a fixed self, suggesting that the "other" represents what is outside or different from oneself, and that this difference is essential for understanding identity. This interplay highlights the relational aspect of existence, where meaning is derived through interaction with the other. Ultimately, Derrida's work prompts a reconsideration of how we define ourselves in relation to those who are different from us.
