There is use when the noun is singular. There are use when the noun is plural.

We can use "there" in 2 ways: 1) there =वहां Ex: there is a tree There is sumone I went there No one is there ( We can use "there" in the beginning or end of the sentences, in both way) 2) we use "there" in a simple sentence when either "subject or object" is missing in the sentence. A simple sentence consist of 3 things: Subject+helping verb+object... So whenever u get a sentence where no subject or no object then u will use "there" Ex: * एक राजा था: here object is missing, एक राजा (subject ) था (helping verb) There was a king. *एक नल है: again object is missing There is a tap *लड़की नही है: again object is missing There is no girl *पानी नही है; again object missing There is no water If there is a singular form u will use "is" or if there is plural form u will use "are" बहुत सारी पतंगे है There r lots of kites. बहुत सारे लोग है There r many people
