There is/are: I want to indicate that something exist or is in certain location

[Tanya_88]

Used when

There is no letter for you in the mailbox.
There is not any letters for you.

Is it important to use “ is not” for plural, and “is not” for singular ?

[Shannongcole]

Yes, it is important to distinguish between plural and singular.

Therefore:

There is no letter for you in the mailbox. or There are no letters for you in the mailbox.

There are not any letters for you. or There is not any letter for you. (In speech, we would tend to use contractions here: aren't/ isn't).

[Tanya_88]

But I found such phrase in textbook - "There isn't any news in her letter" is it wrong?
I think - "There are't any news in her letter" is more suitable. Am I correct?

[Shannongcole]

"There isn't any news in her letter" is correct. Although "news" ends with an "s" and we would think of it as having more than one item, it is a non-countable noun, and must be expressed this way when used alone. Other examples:

"There isn't any milk left."
"There isn't any money on the table."
"There isn't any paint in the bucket."

However, if used with a quantifier, you could use "aren't:"

"There aren't any bottles of milk left."
"There aren't many buckets of paint."

Thanks for explanation, now I understand it

[Tanya_88]

If I speak about plural amount of objects can I use pronouns "some" ?

For instance:

There are some tables in the room

[Shannongcole]

That is correct. When not using the negative in the plural, "some" is appropriate. "Any" should be used with the negative. These can be used with both countable and non-countable nouns:

"There are some tables in the room."
"There aren't any tables in the room."

"There isn't any news in her letter."
"There is some news in her letter."

Be careful of "much" and "many". These depend on the type of noun it is.

"I don't have much news to tell you."
"I don't have much money."

"I don't have many books."
"The store doesn't have many carrots."

There is/are can actually do everything that the verb BE can do. So you could have any variety of forms such as:

There is/are
There was/were
There shall/will/should/must be
There have been
There had to have been, etc
