"There"
* Meaning: Indicates a place or position.
* Usage:
* Adverb of place: "The book is over there."
* Expletive: A word that fills a grammatical role but doesn't add meaning (often used to begin a sentence): "There are many reasons for this."
* Pronoun: Means "that place": "I've been there before."
"Their"
* Meaning: Shows possession or belonging to more than one person or thing.
* Usage: It's a possessive adjective. It's used to indicate ownership or association: "Their dog is very friendly."
Here's a simple way to remember the difference:
* "There" is a place.
* "Their" is about ownership.
Examples:
* There is a beautiful park near my house. (adverb of place)
* There are many ways to solve this problem. (expletive)
* I went to the park, and I was there for hours. (pronoun)
* I borrowed their car for the weekend. (possessive adjective)
* Their house is much bigger than ours. (possessive adjective)
