Common Mistakes: Complete Reference

This page is the consolidated reference. If you have noticed a mistake in your own Italian and want to find the right subpage in seconds, this is where to start. Every recurring error English speakers make is listed here, organized by category, with a wrong/right pair, a one-line diagnosis, and a link to the dedicated drill page.

The errors are also ranked by frequency (how often they occur in beginner-to-intermediate writing) and damage (how much they distort meaning or mark you as a non-native speaker). Pick your priorities accordingly: a high-damage, low-frequency error like piacere inversion is worth fixing on day one; a low-damage, low-frequency one like perché vs perchè can wait until you write your first email.

For the conceptual overview of these patterns and why they happen, see Common Mistakes: Overview.

How to use this page

1. Scan the category headers to find the area where your error lives — morphology, syntax, tense/mood, lexicon, pragmatics.
2. Match your specific error to one of the wrong/right pairs.
3. Click the subpage link for the full explanation and drills.

The frequency/impact matrix at the end ranks the errors so you can sequence your study. Beginners should fix the highest-impact items first (auxiliary, piacere, avere sensations, double negation), then move to the medium-impact ones (subjunctive, prepositions, false friends), and finally polish the low-impact details (capitalization, accent direction).

1. Morphology errors

These are errors in the forms of words: which auxiliary, which article, which agreement ending. They are the most mechanical of the errors and also the easiest to drill once you have spotted the pattern.

1a. Wrong auxiliary in compound tenses (avere vs essere)

English uses have for every perfect tense; Italian splits compound tenses between avere and essere. Motion, change of state, and reflexive verbs take essere; almost everything else takes avere.

Subpage: Wrong Auxiliary in Compound Tenses

1b. Adjective agreement

Italian adjectives agree with their noun in gender and number. English adjectives don't change at all, so English speakers consistently leave the masculine singular form on every noun.

Subpage: Adjective Agreement Errors

1c. Article with singular family member

Singular family terms in Italian take the possessive without an article: mio padre, not il mio padre. Plurals, modified forms, and loro all keep the article.

Subpage: Article with Family Members

1d. Capitalization of nationalities, days, months

English capitalizes Italian, Monday, January. Italian does not.

Subpage: Capitalization Rules

1e. Accent direction (perché vs perchè)

The conjunction perché and a small set of related words take the acute accent, not the grave.

Subpage: Written Accent Marks

2. Syntactic errors

These are errors in sentence structure — where words go, which slot the subject fills, whether a particular construction even exists. They are harder to drill than morphology errors because the underlying English habit is so ingrained.

2a. Pro-drop violation (overusing io, tu, lui)

Italian is a pro-drop language: subject pronouns are normally omitted because the verb ending tells you the subject. Parlo already means "I speak."

Subpage: Overusing Subject Pronouns

2b. Resisting double negation

English avoids stacking negatives: "I don't see anything." Italian REQUIRES stacking: non vedo niente (literally "I don't see nothing"). Drop the non and the sentence is wrong.

The exception: when the negative word precedes the verb, non is dropped — Nessuno è venuto.

Subpage: Italian Double Negation

2c. Piacere inversion

In English the liker is the subject; in Italian the liked thing is the subject. I like the book is structurally the book is pleasing to me in Italian.

The verb agrees with the thing liked, not the liker: mi piacciono i libri.

Subpage: Piacere Inversion

2d. Fare vs dire for asking questions

Italian uses fare una domanda (to make a question), never dire una domanda (to say a question). Or use chiedere (to ask) directly without the domanda noun.

Subpage: Fare vs Dire for Asking Questions

3. Tense and mood errors

These are about which time / modality the verb belongs in. Italian and English carve up the time line and the realm of irrealis differently, so transfer errors are systematic and recurrent.

3a. Subjunctive avoidance (indicativo selvaggio)

The Italian congiuntivo appears after verbs of opinion, doubt, hope, will, and fear — penso che, credo che, spero che, voglio che. English speakers default to the indicative.

Subpage: Subjunctive Avoidance

3b. Presente with da (not present perfect)

For ongoing situations that started in the past, English uses the present perfect ("I have been studying for three years"). Italian uses the simple present with da.

Subpage: Presente + Da Instead of Present Perfect

3c. Future in temporal clauses

After quando, appena, dopo che, when both clauses refer to the future, Italian uses the futuro, not the simple present.

Note: present-tense usage in this context is widespread in colloquial Italian and is generally accepted in everyday speech, but the standard written form requires futuro.

Subpage: Future Tense in Temporal Clauses

3d. Reported future: condizionale composto (not condizionale semplice)

When reporting a past statement that referred to the future, Italian uses the conditional perfect, not the simple conditional. English uses would; Italian needs avrebbe + participle.

Subpage: Reported Future and Condizionale Composto

3e. Overusing sto + gerundio (progressive)

Italian sto + gerundio is for actions ongoing at the reference moment. For habitual or general actions, use the simple present.

Subpage: Overusing Sto + Gerundio

4. Lexical errors

These are errors in word choice — picking the wrong Italian word for a meaning, usually because of a misleading similarity to an English word.

4a. False friends (falsi amici)

Italian has dozens of words that look like English cognates but mean something else. Libreria is "bookshop," not "library." Camera is "bedroom," not "camera." Fattoria is "farm," not "factory."

Subpage: False Friends

4b. Ho vs sono for sensations

English uses to be for hunger, thirst, cold, fear, age. Italian uses avere: ho fame, ho sete, ho freddo, ho paura, ho vent'anni.

Subpage: Ho vs Sono for Sensations

4c. Preposition choices (a, in, di, da)

Italian prepositions don't map cleanly onto English ones. Cities take a; countries take in. Avere paura di (not a); pensare a (not di) for "thinking about a person."

Subpage: Preposition Choices (a/di/in/da)

5. Pragmatic errors

These are errors not in form but in use — getting the grammar right but the social register wrong, or mixing levels of formality within the same conversation.

5a. Mixing tu and Lei

Italian distinguishes informal tu and formal Lei — and switching mid-conversation, or addressing someone with the wrong one, is a real social faux pas. The verb form, the pronouns, and the possessives all have to track.

Subpage: Dare del Tu vs Dare del Lei

Frequency and impact matrix

The table below ranks the errors by how often they occur in beginner writing (frequency) and how much they damage your communication (damage). Higher score = bigger problem.

Suggested study sequence

Working through the errors all at once is overwhelming. Here is a sensible order:

1. Pro-drop and avere sensations — Day one. These two together immediately make your Italian sound more natural.
2. Auxiliary selection — As soon as you start using the passato prossimo. Drill andare/venire/partire/arrivare
   • essere until they are automatic.
3. Piacere inversion — As soon as you want to talk about likes, dislikes, missing someone. The whole inversion family (mancare, bastare, servire) clicks once piacere clicks.
4. Double negation — Drill niente, nessuno, mai with non before the verb until you stop hesitating.
5. Adjective agreement — Whenever you use any adjective, ask yourself whether it ends in the right vowel.
6. Article with family — A small, concrete rule. Knock it out in a single sitting.
7. Prepositions and false friends — Build up gradually as your vocabulary grows. There is no shortcut; these are largely lexical.
8. Subjunctive — When you start using penso che, credo che, spero che. Don't fight the congiuntivo; embrace it.
9. Tense and mood subtleties — Presente + da, futuro in temporal clauses, condizionale composto in reported speech. These are B1+ refinements.
10. Pragmatic register — Tu/Lei consistency, polite forms, fare vs dire for questions. As you start interacting with native speakers, polish these.
11. Spelling polish — Capitalization and accent direction. Save for last; they have minimal impact and are easy to fix in proofreading.

Common Mistakes

This page is itself a common-mistakes index, so the standard "Common Mistakes" section here is the summary table above. For drills, follow the subpage links. For the conceptual overview of why these errors happen and what they have in common — almost all are structural transfer errors, not vocabulary problems — see Common Mistakes: Overview.

Key takeaways

• Italian errors made by English speakers cluster into five categories: morphology, syntax, tense/mood, lexicon, and pragmatics.
• Morphology errors (auxiliary, agreement, articles, capitalization, accents) are the most mechanical — drill the rules and the errors disappear in classes.
• Syntactic errors (pro-drop, double negation, piacere inversion, fare vs dire) require reorganizing how you build the sentence — slower to fix, but immensely high-impact.
• Tense/mood errors (subjunctive, presente + da, futuro in temporal clauses, reported future) emerge as you produce more complex sentences. They are signs of progress, not regression.
• Lexical errors (false friends, prepositions, ho vs sono) are largely a matter of vocabulary maturity. They don't go away with grammar drills; they go away with reading and listening.
• Pragmatic errors (tu/Lei mixing, fare/dire for questions) are about register, not grammar. Get the register right and you sound like an Italian who happens to be a non-native speaker, not a beginner.
• The frequency/damage matrix should guide your priorities: fix high-damage errors first, polish low-damage details last.
• Almost every error here is a structural transfer error — applying an English pattern to Italian where the structures don't align. Once you see the pattern, you can dismantle it.
