'franzliszt2' are you from England, and is english you first language?
Because you appear to be unable to see the difference in the words "no" and "know" an I will guess also the word "now".
"No" means that you are most likely dissagreeing with someone. "No, I don't like milk." As opposed too "Yes, I like milk."
Know(the word you should have used in your last post) is a verb. You use it together with a noun. For instance, in the sentence "He is happy," "is" is the verb and "he" is the noun. "To know" is also a verb:
To Know, I know, I knew, I have known, I had known, I will know, I shall know etc
It means that you are most likely aware of something." I KNOW that Franz Liszt lived from 1811-1886".
"Now", on the other hand deals with time. I am writing this right NOW, not in a few weeks for instance.
Hope this helps.
PS. If english isn't your 1st language I must excuse my self. My english is FAR from perfect either.
