There are changes to my national language in the present.
Singular they is becoming enshrined in the standard not just for persons whose gender identity is unknown (e.g. "Somebody left their phone on the bench") but for persons who do not identify as strictly male or female (e.g. "Drew is bringing their partner, if that's okay"). In addition, "you all"/"y'all" is rapidly going from a regionalism associated with Southern and African-American speech to the preferred second-person plural pronoun and its adoption by people for whom this is not a native element in their speech is having some interesting consequences. (Last week, I heard someone say "your all" where I would have "y'all's"--more than once, so I assume it wasn't an error.)
And that's just the pronouns!
