ux and design terms 'thing explained'

We at Move have been enjoying reading "The Thing Explainer”, a book that puts complicated ideas into simpler terms using only the 1000 most common words in the English language. So I thought I’d try and do a 'thing explainer' around some of the terms in our industry (e.g. 'recruitment' = a job that helps people find work) Here's how I got on:

USER EXPERIENCE. The way to make the use of something more pleasing and easier. This is often done on things such as computers, but not only.

PROTOTYPE. A first or early build of something from which other forms are built.

USER TESTING. A way to see if something works by having people use it. 

WIREFRAMES. A simple drawing that shows where things go and how they are used on things like buildings, computers and phones.

PERSONA. A person who's not a real person, but is like a real person, used to understand a group of real people. They answer questions like 'who are we making this for?' and 'what do they need/want?' to help businesses make better things for real people.

PRODUCT. Something made by someone, used by people for something.

ADVERTISING. A way to sell more things. This can be done on things like TVs, computers and other places.

SOCIAL MEDIA. A place on your phone or computer, but not somewhere you can actually go, where people can send messages to each other and share photos and stories.

DESIGNER. Someone who draws new things and makes them look good and, sometimes, work better. :) 

DIGITAL. Something you can't put in your hand, (or your mouth) but is real. It is made up of the numbers 0 and 1. People use it for many things, often on computers, but not always.

ETHNOCENTRISM. ... No, far too hard!

Give it a go yourselves with the typewriter here. If you have any ideas of other terms we should try and "thing explain", comment below.
