We all want to be good grammarians, because were sensitive writers; we like to please. But if were going to drive our readers wild, we need to learn how to use what weve got.
Lets talk about what it is.
Its: A contraction, short for it is or it has
Its: A pronominal possessive that tells us what belongs to it.
Example: Its a useful condom that comes with its own lube.
Non-example: Its a useful condom that comes with it's own lube.
Now lets talk about the difference.
Example undressed: It is a useful condom that comes with its own lube.
Non-example undressed: The condom that belongs to it a useful one that comes with it is own lube. (or) The condom that belongs to it a useful one that comes with it has own lube.
This is when I moan in anguish rather than pleasure. And look: Im not trying to ridicule. I know youre new to this. You need to be told what to do; you need to be shown. You need me to be gentle. So let me explain.
The apostrophe is a tricky mistress. Sometimes it wants to be used, and sometimes it doesnt. In most cases, we can use it to show possession by tacking it onto the end of a word like this:
Sarahs apple bottom looks so damn fine in those jeans.
But when were using a pronominal possessive, we cant do that. A pronominal possessive is something that stands in for a noun (pronominal = pronoun) and shows ownership (possessive). Pronominal possessives include its, hers, ours, yours and theirs. Lets do this together. Put the its/its where I want them:
Example: ____ hard to bend that way.
Non-example: ____ hard to bend that way.
Example undressed: It is hard to bend that way.
Non-example undressed: The thing belonging to it hard to bend that way.
Youre really good at that.
