There, their or they're

Lots of people often get confused about there, their and they're. These three words sound the same but have different meanings and spellings.  

There 

There is an adverb that means 'in or to a particular place'. There is the opposite of here. 

• Just stay there and don't move! 
• Look at that woman over there. 
• Can I drive there and back in a day? 

There can be used with the verb be to show that something exists. 

• There is a large package on the table. 
• There was nothing in the room. 
• There are a lot of people in the yard. 

We can use there to attract someone's attention. 

• Hello, there! 
• You there! Don't touch them.  

Their 

Their is the possessive form of they. We use it before a noun.  

• Their conversation turned to politics. 
• Their house is very near. 
• Children are playing with their toys. 
• They washed their hands and faces. 
• They had no children of their own.  

They're 

They're is a contraction that is short for they are. The apostrophe takes the place the letter a. 

• They're here till tomorrow.  
• They're worried about these results. 
• They're going to the party. 

In summary 

We use there to refer to places. Their means 'belonging to them'. We can replace they're with they are.
