    Tk is a `Tcl package <http://wiki.tcl.tk/37432>`_ implemented in C
    that adds custom commands to create and manipulate GUI widgets. Each
    :class:`Tk` object embeds its own Tcl interpreter instance with Tk loaded into

    Tk uses Tcl's event queue to generate and process GUI events.
 
-Ttk
-   Themed Tk (Ttk) is a newer family of Tk widgets that provide a much better
-   appearance on different platforms than many of the classic Tk widgets.
-   Ttk is distributed as part of Tk, starting with Tk version 8.5. Python
-   bindings are provided in a separate module, :mod:`tkinter.ttk`.
+   Since version 8.5, Tk also implements the

+   family of widgets. They feature much better, consistent and native look

+   Ttk widgets are recommended for use in new code, with their regular

 Tix
    `Tix`<https://core.tcl.tk/jenglish/gutter/packages/tix.html>_ is an older
    third-party Tcl package, an add-on for Tk that adds several new widgets.
-   Python bindings are found in the :mod:`tkinter.tix` module.

 Tkinter Modules
 ^^^^^^^^^^^^^^^
 
-Most applications will directly use the features provided by :mod:`tkinter`.
-Unless compatibility with very old versions of Tcl/Tk is required, Ttk widgets
-found in :mod:`tkinter.ttk` should also be favoured over their classic Tk
-counterparts.
+:mod:`tkinter` has the core functionality and the bindings for regular Tk
+widgets.
+
+:mod:`tkinter.ttk` has bindings for Themed Tk (Ttk) widgets, and :mod:`tkinter.tix`
+for ones from the Tix add-on.
 
 The :mod:`_tkinter` module provides low-level access to Tcl interpreters in Python,
 using the C interface to the Tcl library. It should rarely be used directly by
