One of the most common problems in the English language is the use of contractions. They are supposed to make life a little easier, but it seems that they don’t do much more than confuse. The case of your vs. you’re is a classic example.
I have said that the easiest way for me to remember the difference between two similar words is to focus on the meaning and use of one. If it’s not the one, then it must be the other. I’ll give you the meaning and use of both, and try to emphasize one to help you remember.
“Your” is possessive. When I use the word, I’m talking about something that belongs to you, or an attribute of you.
Example: Your cat is a beautiful calico.
“You’re” is a contraction. They say repetition is the key to memory: YOU’RE IS A CONTRACTION. That means we’re being lazy. We’ve dropped the letter “a” from the phrase “you are” and replaced it with an apostrophe.
Example: You’re going to need to buy me a new paper to replace the one your cat has destroyed.
See how “you’re”=”you are”? See also the difference between the two words in the same sentence? When I need to remember which word to use, I always say “you-apostrophe-r-e=you are.”
A note about “you’re”: Contractions (combining two words by dropping a letter or two and using an apostrophe) are always considered informal. If you are writing a paper for school (especially for English or certain non-writing teachers!), NEVER use contractions. It’s safer that way. Some writing teachers allow contractions occasionally because of the stated audience for the assignment.
Final tip: when in doubt, spell it out. You can’t spell out “your” because it is the whole possessive word. You can spell out “you’re” because you can write “you are” instead. If you spell it out, you’ll never go wrong.
“Your” is possessive. “You’re” is a contraction.
