Counting nouns
Hi,
I was talking to my friend about a trip to Tartu and asked her: how can I buy a ticket to Tartu? If I were to ask this question on behalf of several people, should I say: How can you buy tickets to Tartu?
I have a trouble determining a singular or plural form of a noun at times.
What is the difference among these sentences and which one is to be used when I mean a general fact that "writer writes book" (In my native tongue, we do not specify the noun's plurality unless it is essential.
1)Writers write books.
2)Writers write a book.
3) A writer writes a book.
4) A writer writes books.
