Italian grammar mistakes are more common than you think — even among native speakers.
On a sunny afternoon in Rome, an eager tourist tried to order his favourite gelato flavour: chocolate. Instead of saying “cioccolato”, he confidently said “cicciotto” — an affectionate term for someone a bit chubby. The vendor chuckled and replied: “Maybe after a few more gelatos!”
One syllable. Completely different meaning.
That’s the beauty and the trap of Italian. A simple swap or misplaced emphasis can change everything. And these kinds of Italian grammar mistakes don’t just happen to tourists — even fluent speakers and native Italians slip up regularly.
In this guide, you’ll discover:
- the 10 most common Italian grammar mistakes
- why they happen (especially for English speakers)
- and exactly how to fix them

Why Italian Grammar Mistakes Are So Easy to Make
Italian is a language of extraordinary depth. Rooted in Latin and shaped by centuries of regional dialects, it carries layers of complexity beneath its melodic surface.
What makes Italian grammar mistakes so common — even for natives — is the sheer number of agreements, conjugations, and context-dependent rules packed into everyday speech.
From northern dialects influenced by French and German, to southern ones carrying traces of Greek and Arabic, the diversity is astounding. This richness is exactly what makes Italian so expressive… and so easy to get wrong.

The Top 10 Italian Grammar Mistakes
⚠️ Mistake 1: Confusing “Sono” and “Sto”
This is one of the most classic Italian grammar mistakes for English speakers — because both can translate to “I am.”
“Sono” describes inherent qualities, identity, or permanent states:
- Sono un insegnante. — I am a teacher.
- Sono italiano. — I am Italian.
“Sto” describes temporary states, feelings, or locations:
- Sto bene. — I am well.
- Sto a casa. — I am at home.
❌ Wrong: “Sono bene!” (I am a good person — not what you meant!) ✅ Correct: “Sto bene!” (I am well / I’m doing well.)
👉 Rule of thumb: if the state can change, use sto. If it defines you, use sono.
⚠️ Mistake 2: Mixing Up “Essere” and “Avere” as Auxiliaries
In English, the past tense uses “have” for everything. In Italian, some verbs take avere (to have) and others take essere (to be) — and getting this wrong is one of the most frequent Italian grammar mistakes.
❌ Wrong: “Ieri sono mangiato la pizza.” ✅ Correct: “Ieri ho mangiato la pizza.” (I ate pizza yesterday.)
❌ Wrong: “Ho andato al mercato.” ✅ Correct: “Sono andato al mercato.” (I went to the market.)
👉 Key rule: verbs of motion, reflexive verbs, and most intransitive verbs use essere. Transitive verbs (those with a direct object) usually use avere.
⚠️ Mistake 3: Dropping the “H” in “Ho”, “Hai”, “Ha”, “Hanno”
A subtle but visible Italian grammar mistake — especially in writing.
The forms of avere (to have) in the present tense all start with a silent H:
- ho (I have), hai (you have), ha (he/she has), hanno (they have)
Without the H, these become completely different words:
- o = or | ai = to the | a = to | anno = year
❌ Wrong: “Ieri o mangiato…” ✅ Correct: “Ieri ho mangiato…”
👉 Fix: read Italian texts regularly. The H becomes instinctive quickly with exposure.
⚠️ Mistake 4: Skipping Mandatory Contractions
In Italian, combining certain prepositions with articles is not optional — it’s a grammar rule.
| Preposition + Article | Contracted Form |
|---|---|
| a + il | al |
| di + il | del |
| in + i | nei |
| su + la | sulla |
❌ Wrong: “Vado a il mercato.” ✅ Correct: “Vado al mercato.” (I’m going to the market.)
👉 These preposizioni articolate must be memorised. There are no exceptions for the mandatory ones.
⚠️ Mistake 5: Saying “Io Sono” When Introducing Yourself
One of the most charming yet unnecessary Italian grammar mistakes — copying the English “I am” structure.
❌ Unnatural: “Io sono Marco.” ✅ Natural: “Mi chiamo Marco.” (My name is Marco / I’m called Marco.)
👉 While Io sono Marco is technically understood, Mi chiamo is what Italians actually say. Using it instantly makes you sound more native.
⚠️ Mistake 6: Getting Tricked by Grammatical Gender
Italian gender doesn’t always follow logic — and these traps cause many Italian grammar mistakes for learners.
Some words that look masculine are feminine, and vice versa:
- il problema — masculine (not la problema)
- la mano — feminine (not il mano)
- il clima — masculine
- la radio — feminine
❌ Wrong: “La problema è seria.” ✅ Correct: “Il problema è serio.” (The problem is serious.)
👉 Best fix: learn gender with context, not in isolation. Always memorise the article alongside the noun.
⚠️ Mistake 7: Using “Favorito” Instead of “Preferito”
A classic false friend that trips up even advanced learners.
❌ Wrong: “Il mio libro favorito è questo.” ✅ Correct: “Il mio libro preferito è questo.” (My favourite book is this one.)
👉 Favorito exists in Italian, but it’s used only in competitive contexts — like the favourite team to win a tournament. For personal preferences, always use preferito.
⚠️ Mistake 8: Misplacing Clitic Pronouns
Clitic pronouns (lo, la, li, le, mi, ti, ci, vi, ne) have very specific rules about where they go — and misplacing them is a surprisingly common Italian grammar mistake.
❌ Wrong: “Voglio vedere lo.” ✅ Correct: “Voglio vederlo.” (I want to see it/him.)
When used with an infinitive, the clitic attaches to the end of the verb (dropping the final -e).
When used with conjugated verbs, it goes before: ✅ “Lo vedo.” (I see it/him.)
👉 This takes time and exposure to internalise — listening to native Italian content is the fastest fix.
⚠️ Mistake 9: Avoiding the Subjunctive (Congiuntivo)
Many learners — and even some native speakers in informal speech — avoid the congiuntivo because it feels complicated. But skipping it is a clear Italian grammar mistake in formal and written Italian.
The subjunctive is required after expressions of opinion, doubt, wish, or emotion:
❌ Wrong: “Penso che tu sei stanco.” ✅ Correct: “Penso che tu sia stanco.” (I think you are tired.)
❌ Wrong: “Voglio che lui viene.” ✅ Correct: “Voglio che lui venga.” (I want him to come.)
👉 Start by memorising the most common triggers: penso che, credo che, voglio che, è importante che.
⚠️ Mistake 10: Ignoring Double Consonants (Geminazione)
This is one of the most underestimated Italian grammar mistakes — particularly in pronunciation. Double consonants in Italian are not just spelling quirks; they change meaning entirely.
- casa (house) ≠ cassa (cash register / crate)
- pala (shovel) ≠ palla (ball)
- nono (ninth) ≠ nonno (grandfather)
Getting this wrong in speech can cause genuine confusion — or a lot of laughter.
👉 Fix: listen actively to native speakers and shadow their pronunciation. Pay attention to how long they hold consonant sounds.
How to Fix These Italian Grammar Mistakes for Good
Knowing the mistakes isn’t enough — you need to actively correct them.
🎧 Active listening: Watch Italian films, YouTube channels, and podcasts with attention. You absorb natural structures without conscious effort.
📝 Targeted practice: Focus your exercises on your weak spots — auxiliaries, contractions, subjunctive. Don’t spread yourself too thin.
🗣️ Speak with natives: Platforms like italki let you practise with real Italian tutors at affordable rates. Nothing fixes grammar faster than real conversation.
📚 Structured study: A clear study plan prevents you from repeating the same Italian grammar mistakes for months. Small daily sessions beat sporadic cramming every time.
✍️ Write in Italian: Even short daily journal entries help you spot and fix recurring errors.
Conclusion
Italian grammar mistakes are not a sign of failure — they’re proof that you’re engaging with one of the world’s most nuanced and beautiful languages.
Even native speakers from Milan to Palermo slip up with subjunctives, double consonants, and auxiliary verbs. The difference between a good learner and a great one isn’t perfection — it’s the awareness to spot, understand, and correct these mistakes over time.
Now that you know these 10 Italian grammar mistakes, you’re already ahead of most learners.
