Another writing error that 1) won’t get fixed by spellchecker, 2) will most definitely make your writing look less than stellar, and 3) is easy to fix all by yourself. Here’s how: Just think about what you’re trying to say.
“Your” is a possessive pronoun, as in “your book” or “your blog.”
“You’re” is a contraction for “you are,” as in “you’re messing up your writing by using your when you really mean you are.”
Take the test. Read the sentence out loud and if you can’t replace “your” with “you are,” then you’re using the wrong word. Replace it.
It’s as easy as that.
