I choose the words: screen, button, turn on, turn off, plug and unplug.
I think these six words are more useful in our common life, for example: if you use to work with computers, with English programmes, is habitual to listen or see the screen word.
Button has the same explanation of screen, but you can find this word in some songs (Chemical Brothers).
Turn on and turn off are common if you are talking about any thing from your house, or from some technological devices we have.
Plug and unplug are some curious form me, some years ago I listen for the first time a record 'unpluged', I never listen a word like this so from this time on I'm used to use this words.
