Valmy gets a paper from the safe - a paper with a drawing on it.

-------------------
What is the meaning of 'paper' in the sentence? Do we have to use 'a' before 'paper' or not?

Yes, you need "a" before "paper."

The paper could be some kind of certificate (birth certificate, death certificate, stock certificate, etc.) or perhaps a will or some other type of legal document.

Thank you for your help.

Can a paper mean a piece of paper?

Yes, but if it's in a safe, it's probably not a blank piece of paper! It undoubtedly has legal or financial information on it; otherwise, there'd be no reason to keep it in a safe.

The paper has a drawing of Picasso's. In this case, isn't it a piece of paper with his drawing on it? When the piece of paper has a drawing on it, can we use 'a paper'?

If you refer to it as "a paper," the assumption will be that it's blank. If you want to be specific (which is always a good idea!), then you should indicate what the paper is -- that is, what it has on it.

In this case, you should call it "a sketch by Picasso" -- and people will know it's on paper.

I am in 2nd grade.I no what your talking about.

In the sentence, the word "paper" refers to a sheet or piece of material that is used for writing, drawing, or printing on. Now let's address the use of the word "a" before "paper."

Articles like "a" or "an" are used to indicate that we are referring to a non-specific or unspecified item. In this case, the sentence states that Valmy gets a paper from the safe. Since there is no prior mention of a specific paper or any particular paper mentioned in the sentence, the indefinite article "a" is appropriate and grammatically correct.

However, if there were a specific paper mentioned or if the sentence specified a particular paper (e.g., "Valmy gets the paper with a drawing on it from the safe"), then the definite article "the" would be used instead of "a."

So, to summarize, in this sentence, "a" is used before "paper" because it refers to an unspecified or non-specific paper.
