Consider the sentence “If you’re writing it you’re, you’re writing it right. " You are doing something when you write, and thus the contraction you’re is correct. You could also try something like the sentence “Your Outraged Unicorns Race,” where the first letter of each word spells out the correct usage. Because the unicorns belong to you, they’re your unicorns.
“You’re a good friend” means “You are a good friend. " “I don’t know what you’re talking about” means “I do not know what you are talking about. "
“Is your stomach growling?” “Your book is on the table. "
In other words, saying “Your very kind” will almost never be correct. “Your very kind” would only be correct if someone were describing a noun, as in “Your nice son brought me my coat. " Here, your nice is correct because nice is describing the person’s son.
“I can’t read you’re handwriting. " Incorrect, because the contraction for you are is being used in place of the possessive form of you. “I can’t read you are handwriting”’ doesn’t make sense. It should be replaced with your. “If your hungry, then you should probably eat something. " Incorrect because there is no possession in question. You can be hungry, but in English you don’t possess hunger. This passes the replacement test. Rewriting it with you are fits. Your should be replaced here with you’re, or you are. “I think your very smart. " Again, incorrect. The “very smart” does not belong to the person that you are talking to — this doesn’t make any sense. Replace your with you’re, or you are. “I’m smarter than you’re” Correct, because the contraction for you are has been used in place of the possessive form of you. However, this unconventional usage is likely to confuse people, so avoid ending a sentence with you’re even if it’s grammatically correct.
