One small mistake. One big message.
๐ Choose your language
What Students Say. What the World Hears.
Every teacher knows this moment:
A student says, โYou was there yesterday.โ Or worse: โWhat you is?โ
Itโs a small slip.
It seems harmless.
And most people would just say, โOops, wrong verb form.โ
But hereโs what I tell my students:
This isnโt just about grammar. Itโs about how you make people feel.
And sometimes, you donโt sound โfunny.โ You sound like youโre insulting them.
Let me show you why.
The Line Between โWrongโ and โOffensiveโ
Mistakes like you was or you is are common.
They appear in music, movies, TikTok, and casual speech โ especially in dialects like African American Vernacular English (AAVE), London street slang, or certain Southern U.S. regions.
But outside those contexts?
If you say โyou isโ to a stranger in a formal setting โ or even in a street argument โ it can come across not just as incorrectโฆ
โฆbut as disrespectful.
The Film Example That Says It All
I once saw a scene that made it clear:
โ โDo you know what I am?โ
โ โI donโt know who you are. I know what you is.โ
Not who you are.
But what you is.
The message:
Youโre not a person. Youโre a thing.
It wasnโt the grammar that hurt.
It was the intention, wrapped in broken grammar.
And yes โ it hit hard.
Whatโs So Bad About โYou Isโ?
In standard English, โyou isโ doesnโt exist.
We say:
- โ You are
- โ You were
When someone uses โyou isโ, it can sound like:
- You donโt respect the person youโre talking to
- You donโt care enough to speak properly
- Youโre mocking them, on purpose
Even if you donโt mean it that way, thatโs how it can come across.
Cross-Language Parallels: Itโs Not Just English
Letโs be clear: this idea isnโt unique to English.
๐ท๐บ Russian
- ะัะพ ัั ัะฐะบะพะน? โ โWho are you?โ (harsh but still personal)
- ะงัะพ ัั ัะฐะบะพะต? โ โWhat are you?โ (dehumanizing)
๐บ๐ฆ Ukrainian
- ะฅัะพ ัะธ? โ neutral
- ะฉะพ ัะธ ัะฐะบะต? โ loaded, insulting
๐ฉ๐ช German
- Wer bist du? โ correct, respectful
- Was bist du? โ rude, strange, used to belittle someone
- Confusing โdu warโ instead of โdu warstโ sounds illiterate or arrogant โ same effect as โyou wasโ
So yes โ switching โwhoโ to โwhatโ, or โareโ to โisโ, sends a message.
Even if your grammar is weak, your words still carry emotional weight.
Why I Tell My Students This on Day One
Most teachers will just say, โThatโs wrong.โ
I say:
โIf you say this to someone in a tense moment โ they may not correct you. They may just walk away. Or punch you.โ
Itโs not about being perfect.
Itโs about being aware.
Because language is not only rules โ itโs respect.
If you say you is, you was, what you is โ it can sound like:
- You donโt respect the other person
- You learned from memes, not people
- Or worse โ youโre trying to be tough, and failing badly

Real English Means Knowing What NOT to Say
I donโt teach language just to pass exams.
I teach it to survive.
To connect. To build trust. To avoid mistakes you didnโt even know you were making.
When you learn English with me โ I wonโt just tell you whatโs right.
Iโll tell you why it matters.
Because you donโt just need grammar.
You need social instinct in a new language.
And thatโs what I give my students โ from day one.
Speak free. Global learning. Personal approach.
