If you have a compact disk with no recordings, is it a "clean" CD? If it already has as many recordings as it can hold, is it "full"? If it already has some files on it, is it a "burnt" CD? What are some other very common words about CDs?
If I were a native speaker of English, I would never shut up. :-)
It's a blank CD until you record something onto it.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
