# Built-in Functions
This section lists the functions built into the Nix expression
evaluator. (The built-in function `derivation` is discussed above.)
Some built-ins, such as `derivation`, are always in scope of every Nix
expression; you can just access them right away. But to prevent
polluting the namespace too much, most built-ins are not in
scope. Instead, you can access them through the `builtins` built-in
value, which is a set that contains all built-in functions and values.
For instance, `derivation` is also available as `builtins.derivation`.
This section lists the functions built into the Nix language evaluator.
All built-in functions are available through the global [`builtins`](./builtin-constants.md#builtins-builtins) constant.
For convenience, some built-ins are can be accessed directly:
- [`derivation`](#builtins-derivation)
- [`import`](#builtins-import)
- [`abort`](#builtins-abort)
- [`throw`](#builtins-throw)
