there is/there are

Structure and Use (there is/are)
There are and there is are forms used to express “existence of”. The structure is:
There + verb to be (is for SINGULAR nouns ; are for PLURAL nouns)
Examples:
- There is a guitar in my room. (A guitar “exists” in my room)
- There are two chairs in my room. (Two chairs “exist” in my room)
The following chart is the forms of “there is/are” in positive (+), negative (-), and questions (?)

Singular	Plural
(+) There is a {chair, book, man}	There are [some] {chairs, books, men}
(-) There isn’t a {laptop, bathroom}	There aren’t [any] {laptops, bathrooms}
(?) Is there a {problem, shirt}	Are there [any] {problems, shirts}

NOTES:
This table is only for COUNTABLE NOUNS. In the future we will talk about uncountable nouns. For this level when you use “there is” use the article “a”. In the plural “there are” you can use “some” for positive and “any” for negative and questions (some/any) is optional
