It helps to understand how it actually works. The s in its does not point towards possession, it is simply part of the word "its". My, His, Hers, Ours, Yours, Theirs, Its. Not Me's, He's, She's, Us's, Your's, Their's, It's. English is an easy language. Most languages use a lot more words than all that to convey all that. English speakers don't have to deal with the singular second person, with a separate objective no…
The brain is an incredible pattern recognition machine. The regular form of possessive is 's. That is, when it's right to add an s to a noun indicate possession we add an apostrophe. This is more regular than a lot of english rules. So now there are pronouns. They are a bit weird, carrying some strange stuff from germanic languages about changing the word based on the case (sometimes). For the most part, it's pretty…
He. She. It. That's all you have to deal with. You have to know whether the subject is male, female, or indeterminate in some way. There's maybe a couple of exception (like boats being refered to as She and such) but other than that, you literally go by genitalia.
In most other languages you have to take into account whether the subject is male or female and whether the subject should be referred to as plural as a form of politeness; if their sex is unknown or indeterminate you have to know whether the word itself is masculine or feminine (or neutral!). Shall I go on?
Oh and that's not even mentioning languages with different grammar rules for the various different kind of persons. You have singular and plural. That's it. Some languages have singular, plural-few, plural-many, some, none, all, and they all have their different grammatical rules.
Boo-hoo, you gotta remember whether to put an s or not. Some languages have to remember dozens of different suffixes to put at the end of the word depending on the forementioned rules and a bunch more, including how the word itself is written.
Come on.
