 ==================================================
 
 There are situations where it is necessary to report several exceptions that
-have occurred. This it often the case in concurrency frameworks, when several
+have occurred. This is often the case in concurrency frameworks, when several
 tasks may have failed in parallel, but there are also other use cases where
 it is desirable to continue execution and collect multiple errors rather than
 raise the first exception.

 Improved Error Messages
 =======================
 
+* Improve the error suggestion for :exc:`NameError` exceptions for instances.
+  Now if a :exc:`NameError` is raised in a method and the instance has an
+  attribute that's exactly equal to the name in the exception, the suggestion
+  will include ``self.<NAME>`` instead of the closest match in the method
+  scope. Contributed by Pablo Galindo in :gh:`99139`.

 * Improve the :exc:`SyntaxError` error message when the user types ``import x
   from y`` instead of ``from y import x``. Contributed by Pablo Galindo in :gh:`98931`.
