The Elu" system () is based on a set of linguistic proposals created with the purpose of preparing the Portuguese language with a neuter grammatical gender. The most prominent proposal is the personal neopronouns elu, delu, nelu, and daquelu", intended to be a proposal for how to refer to non-binary people (whose gender identity is not male or female) or whose gender is unknown, or irrelevant, as well as groups with different genders, without resorting to the "generic masculine". These proposals can be used by and for anyone, regardless of gender.
