+
+   A special form representing the value that results from evaluating a
+   type expression.
+
+   This value encodes the information supplied in the type expression, and
+   it represents the type described by that type expression.
+
+   When used in a type expression, ``TypeForm`` describes a set of type form
+   objects. It accepts a single type argument, which must be a valid type
+   expression. ``TypeForm[T]`` describes the set of all type form objects that
+   represent the type ``T`` or types assignable to ``T``.
+
+   ``TypeForm(obj)`` simply returns ``obj`` unchanged. This is useful for
+   explicitly marking a value as a type form for static type checkers.
+
+   Example::
+
+      from typing import Any, TypeForm
+
+      def cast[T](typ: TypeForm[T], value: Any) -> T: ...
+
+      reveal_type(cast(int, "x"))  # Revealed type is "int"

 ------
 
+* :pep:`747`: Add :data:`~typing.TypeForm`, a new special form for annotating
+  values that are themselves type expressions.
+  ``TypeForm[T]`` means "a type form object describing ``T`` (or a type
+  assignable to ``T``)". At runtime, ``TypeForm(x)`` simply returns ``x``,
+  which allows explicit annotation of type-form values without changing
+  behavior.
+
+  This helps libraries that accept user-provided type expressions
+  (for example ``int``, ``str | None``, :class:`~typing.TypedDict`
+  classes, or ``list[int]``) expose precise signatures:
+
+  .. code-block:: python
+
+     from typing import Any, TypeForm
+
+     def cast[T](typ: TypeForm[T], value: Any) -> T: ...
+
+  (Contributed by Jelle Zijlstra in :gh:`145033`.)
+
 * The undocumented keyword argument syntax for creating
   :class:`~typing.NamedTuple` classes (for example,
   ``Point = NamedTuple("Point", x=int, y=int)``) is no longer supported.
