Web design, usability, UI/UX?

Question

User interface

Can you answer my question:
Imagine a menu:
Category 1. Web design
Category 2. Usability
Question:
Should I add:
Category 3. UI / UX
If, following the concepts, terms
UI = web design
UX = usability
Or can make a subcategory:
Web design > UI
Usability > UX
or simply without subcategory
1. Web design (UI)
2. Usability (UX)
Or maybe I should forget about these Users, the theme is web, the interface of TV remotes is not mine.
Confused ...
Such a kind of understandable answer, but I don’t understand ...)

Answer 1

UI - user interface.
UX is user experience.
Experience - sensations, experiences, information received.
Usability is a property of an interface that affects the experience. Experience can be more or less good or bad, easy or difficult, <other life adjectives>. Usability, in Russian, is the ease of use of the interface.
Webdesign is the design of the user interface called "website".
Interface - a layer between the user and the device that allows the user to interact with the device. The device can be anything (a faucet in the bathroom, for example, water control knobs - a faucet interface).
I don’t know what the menu is in the subject, and why indicate all this there, but I hope it helped to understand the terms.
