# Scoping rules
|
|
|
|
Nix is [statically scoped](https://en.wikipedia.org/wiki/Scope_(computer_science)#Lexical_scope), but with multiple scopes and shadowing rules.
|
|
|
|
* primary scope: explicitly-bound variables
|
|
* [`let`](./syntax.md#let-expressions)
|
|
* [`inherit`](./syntax.md#inheriting-attributes)
|
|
* [function](./syntax.md#functions) arguments
|
|
|
|
* secondary scope: implicitly-bound variables
|
|
* [`with`](./syntax.md#with-expressions)
|
|
|
|
Primary scope takes precedence over secondary scope.
|
|
See [`with`](./syntax.md#with-expressions) for a detailed example.
