We learned proper grammar in like, fifth grade, right? So why is it that I STILL see college students (yes, I'm talking 18-22 year old men and women) saying for example, "Me to" and "your so pretty." It's time for a lesson on the importance of grammar.
They're, their, and there
They're: a contraction for "they are" - i.e. "They're in the living room."
Their: use when indicating possession - i.e. "My parents are in their room."
There: (1) use when referring to a place - i.e. "I've never been there before." (2) with "to be" verbs (be, is, am, are, was, were, will be), which indicates the existence of something - i.e. "There is a dog in the yard."
If I read one more text message that says "I want to go their," I will gouge my eyes out (okay, a bit dramatic, but COME ON, PEOPLE).
Your and you're
Your: use when indicating possession - i.e. "The book is yours." or "Your eyes are pretty."
You're: a contraction for "you are" - i.e. "You're beautiful."
There is a difference between knowing your sh*t and knowing you're sh*t.
To and too
To: a versatile preposition meaning (1) toward, (2) until, and (3) reaching as far as - i.e. "The party lasts from 2 to 6 p.m." or "I'm going to the movies."
Too: an adverb that means (1) additionally, (2) also, or (3) excessively - i.e. "I want to go, too." or "There is too much glitter on this poster."
Of and off
Of: a preposition used to indicate a point of reference or to point out the elements of another object - i.e. "Go south of the border." or "Cup of water."
Off: a preposition and an adverb used to describe the end of something or a physical separation from a position of rest - i.e. "Turn off the music." or "It's just off the corner of Maple."
