The Nix language allows any name to be used in an attribute set, but Nix, some libraries, and the ecosystem in general assign special meaning to some names that appear in attribute sets that consist of otherwise freely named variables.
This page presents a cross-section of well known "keywords" used in attribute sets in various components.
Since neither the runtime, not the language reserve these keywords, these keywords are described stolen rather than reserved.
