That one is a bad one. The incorrect use of there, their, or they're. English is one mutt of a language and quite complicated at times.

U = you
R = Are
Or when they mispell on purpose.
It's not cute.

"Alot." A lot of people make this mistake. It makes them look incredibly stupid.

Text speak. I speak English, not Acronym.

Its and it's, their, they're, and there, alot, etc.

Its not they're fault there so ignorant..your going to have trouble if you're not reading alot.

On the other hand I'm going to plug the Thai language..if English were this easy, there'd be no reason to teach grammar; no capital letters, punctuation, verb tenses, spaces between words, or even arbitrary left to right writing.

Most sentences involve few words. Instead of children in class saying "Don't block my view," they say, "Yah ban" (stop bulking). Instead of saying, "I don't want to do that!" they say "Mai ow." (no want).

Few, if any, pronouns are used. Instead, people use words that reflect the person's age in relation to the speaker, like "pee" and "nong" (elder and younger) and people use self-identifying reflexive pronouns with each sentence, identifying which gender they are claiming at the moment.

For example, "Jat bie, Kah" (I'm going, female reflexive pronoun).

No need to even guess someone's gender, and it's a good thing. I often can't tell, and it doesn't matter.

I still get who and whom confused.

There, They're, Their
The whole your group...
I couldn't never stand double negatives either.
Irregardless instead of Regardless (They screwed the pooch on that so many times they finally added irregardless to the dictionary!)

To wit: "first annual"--no such thing.

I used to be a grammar nazi. Now I really don't care. Unless there are many errors in a sentence or two.

not grammar but loose instead of lose fcks sake

People here tend to say "I seen" instead of "I saw".

Its and it's.

But it's so refreshing to read something intelligent that I wouldn't mind if they used the number 8 to replace 'ate' and 2 instead of 'to'.

Yup, the you're/your thing is a thorn in my side as well. I inwardly cringe each time I see the mix up.

Then, there is confusing then and than, or are and our.

And adding an apostrophe in a word to show plural - like cow's, instead of cows. Cow's what !!??

Text speak, or abbreviations, used in un-text regular writing. Ugh !

There are so many, but one of the most egregious that I hear regularly and see in emails is the use of "myself" in place of both "I" and "me."

It is a sad reflection on the quality of the English language being taught both here in the United Kingdom of the British Isles and Northern Ireland and that of the United States of America, that we then revert to Latin, for example Verbatim

Okay, and the word "and" ends with a "D!"

it's rampant, but i ignore it unless the person is a troll and i am about to block him/her anyway. then all bets are off. but one i recently did not ignore (and got called names for pointing out quite gently) was "since" for "sense." that's no typo. that's ignorance. "could of" for "could have" raises the hairs on the back of my neck because it didn't used to be so rampant -- it was sufficiently unusual that i actually was able to identify a real-life rather dangerous stalker because of it. it was idiosyncratic to her at the time, or was unusual enough to be considered so. on tv, i get crazy when the subject doesn't match an introductory clause. examples: "as a child, my father taught me to spell." oh really, your father had a child when he was a child? "finding the cat quivering in the shadows, it meowed." it found itself and then meowed? stuff like that. and i don't mean this shows up in interviews, in which people may speak off the cuff and not be strictly grammatical. no, i am talking about scripted stuff, that gets written down, typed up, presumably proofread (yeah, these days that means spellcheck, which isn't the same thing!) and then read by someone who has a nice voice but hasn't got a clue what he's saying. that really depresses me.

just between you and me, "just between you and i" is not a new phenomenon but it still rankles. it hurts i to see/hear it.

someone mentioned "i seen." does no one go to SCHOOL anymore?

every day, i see "everyday" used as an adverb instead of every day. it's an everyday thing, i guess; spelling it as one word makes it an adjective.

one more thing, also on tv. two times. no one will say "twice." it's always two times. and there are fewer comparatives and superlatives. it's always "more toasty" instead of toastier, "the most easy" instead of the easiest. is this deliberate? how did this happen?

g

p.s. i don't make initial caps in casual writing, such as social media posts. some of it is the remainder of an old stylistic conceit from my teenhood but most of it is the arthritis that plagues my hands. it can't be as hard and annoying to read AS ALL CAPS, THOUGH. THAT HURTS MY EYES!

My pet peeve is adding "at" to the end of a location question. "Where is it at?" vs just "Where is it?" I'm sure my peevishness about it is because my ex-husband used to say it, along with his entire family, and so any perspective dates after our divorce got nixed if they had that particular grammar habit.

All of the aforementioned, as well as 'feels' being used as a noun (which I know is deliberate and therefore pisses me off even more) and those '[person or group] be like [picture]' memes. Argh.

People tend to assume this is something that bothers me; in fact, it doesn't - in the majority of cases it's entirely possible to understand what a person is trying to say provided they have a basic grasp of grammar. If someone says "me and her went on holiday" rather than "she and I went on holiday" I know what is meant either way and am far more interested in where they went on holiday and what happened there than how I've been told.

Jee, guere dho'I estart?? ????

to, too

"Try and"

I actually don't mind grammar mistakes. They do make me think that the person is uneducated, or trying to pretend to be a native English speaker when they are, in fact, a non native English speaker trying to scam me.

Recursive acronyms bother me: "ATM machine". Or adding to the the obvious to create an overdraw: "hot water heater". It also bothers me when people selectively label cents as singular when there are more than just one cent: "your change is 45 cent".

But unfortunately I just let it go; not creating unnecessary conflict to no benefit.

I could not care less I only care about what you are trying to say. (And it should be 'grammatical',) Sorry only kidding.
