This chapter, we'll tackle the annoying words that are commonly interchanged. And no, it doesn't mean you can substitute one for the other.

1. "Your" and "You're"

"Your" is a possessive pronoun, just like "Mine," "His," and "Hers." It connotes ownership.

"You're" is a contraction of the words "You are." [Just like a shortcut.]

Examples: Kyuhyun's bag --> Your bag

You are crazy --> You're crazy

Wrong examples:  Your cute --> This should be "You are cute."

You're mother --> This should be "Your mother."

2. "Their," "They're," and "There"

"Their" is a possessive pronoun, as explained above.

"They're" is a contraction of the words "They are."

"There" pertains to a place, like "There she goes," or "He's in the closet over there."

3. "Were," "We're," and "Where"

"We're" is a contraction of the words "We are."

"Were" is a verb, plural as a past tense of the word "be," and singular when used with the word "you."

"Where" pertains to a place.

Examples: We're here --> We are here

You were there.

Sungyeol and L were singing. --> Sungyeol and L will be singing. (future tense)

Were are you--> Where are you?

I'll add more when I think of them... [As I read...]
