Question

I was wondering if these were official changes, or not. Few more examples, maybe, but can't think of them now.

Answer 1

The plural of parent is parents, not parent's.

Their is the possessive of they.

There is a word to show location.

Just because you see various forms of word usage does not mean it is accurate or acceptable or an alternate form.  If in doubt, consult a reputable source for English grammar.
