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

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 !

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

Text speak. I speak English, not Acronym.

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."

not grammar but loose instead of lose fcks sake

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

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.

None, let go of the small things in life

1st one is THERE IS NO FUCKING "T" IN ACROSS...and if I hear "NUCULAR" one more time ...I'M GOING TO GO "NUCLEAR"...oh...and let us not forget "IRREGARDLESS"...it is "REGARDLESS" YOU DUMB ASS MOTHERFUCKING TWATWAFFLES !

The use of "or" as an equivalent. "Or" inside parentheses with acronyms. "Or" used to finish an inclusive list. All very wrong especially in science texts. These are not allowed in legal docs.

"6 kilometers, or 3.7 miles." Not an "or." They are the SAME!

The Best Place On Earth (or TBPOE). No "or" needed.

"This medicine can cause heart attack or stroke." Oh! I get a choice? Really?

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

"Try and"

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.

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

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.

No one is perfect, grammatically or otherwise. Mistakes are bound to be made. What triggers me aren't the mistakes but rather those who are content with mediocrity. In radio, we called it 'lazy mouth'... Things like pronouncing "picture" as "pitcher", and midwestern-isms like "farty", "fark", "harse" for "forty", "fork", and "horse", respectively.

It's usually autocorrect that screws me up. Sometimes I just leave words out completely. Like "I'm buying your bullshit." I left out the NOT. Did that one today.

Please don't axe me a question unless I can hachet you the answer.
Me and Pete went to the store. No! Pete and I went to the store. Or Pete went to the store with me.

Two things that annoy me slightly are:
Use of adjectives in place of adverbs, eg he runs 'fast'.
Modern use of 'alternate' in place of 'alternative'.

Mine is the rise of "less' and decline of "fewer". Drives me crazy. Fewer is a number and less is an amount but now so many people, even those educated ones just use less.

Ooooh! Wanton use of the apostrophe gets under my skin eve'ry time!!!

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 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.

to, too

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