Today we’re going to have a little lesson about grammar.
It’s is a contraction. It is a contraction of the words “it” and “is,” and is used like this: It’s raining outside this morning, so I will have to wear my jacket.
Its is a possessive pronoun. It is a word that is not a contraction. It is used like this: The cat was chasing its tail in the living room.
I can see how it would be easy to make these mistakes if you weren’t paying attention or weren’t taught these things or are simply lazy. However, it bothers me to no end to see extremely well thought out blog posts and comments with errors like this. It’s not hard to do a bit of proofreading. Please don’t cheapen your argument with simple, lazy errors.
Next time we’ll cover “your” and “you’re.”
