If Italian grammar has a reputation for being friendly, Italian irregular verbs are the part that ruins the friendship. You learn the neat -are, -ere, -ire endings, you feel unstoppable, and then andare becomes vado, fare becomes faccio, and essere becomes whatever it feels like that day. The good news, in 2026 as ever: these verbs are not random. They follow a small number of repeating patterns, and once you see the patterns you stop memorising hundreds of forms and start recognising maybe seven families.

This guide covers what irregularity actually means, the high-frequency verbs to learn first, the stem patterns that predict most forms, irregular past participles, and a drill method our tutors use with real students.

What Makes a Verb Irregular in Italian?

A regular Italian verb keeps its stem and takes predictable endings. Parlare drops -are and adds -o, -i, -a, -iamo, -ate, -ano. Nothing surprising happens.

An irregular verb breaks that deal in one of three ways:

• The stem changes. Venire becomes veng- in vengo and vengono.
• The endings are unusual. Essere and dare keep forms inherited straight from Latin.
• Only some tenses misbehave. Many verbs are irregular in the present and past participle but perfectly regular in the imperfect.

That last point is the one most learners miss. Fare looks terrifying until you notice its imperfect (facevo, facevi, faceva…) is completely predictable. Most Italian irregular verbs belong to the second conjugation in -ere, which is exactly where the tricky past participles live too.

The 10 Irregular Verbs to Learn First

Frequency beats completeness. A handful of verbs carries an enormous share of everyday Italian, and they are almost all irregular. Learn these ten in the present tense before you touch anything else.

Read that table across and something jumps out: noi and voi are almost always the well-behaved ones. Andiamo, andate. Veniamo, venite. Potete, dovete. The irregularity clusters in the singular forms and in loro — because those are the stressed forms, and stress is what warped the stem historically. If you are ever stuck mid-sentence, the noi form is your safest guess.

Seven Patterns That Predict Most Forms

Here is where memorisation turns into logic. Nearly all Italian irregular verbs fall into these families.

1. The -go / -gono group

Verbs whose stem ends in -n- or -l- insert a g in the io and loro forms only: tenere → tengo, tengono; rimanere → rimango, rimangono; salire → salgo, salgono; scegliere → scelgo, scelgono. Everything in between is regular.

2. The -isc- infix

Third-conjugation verbs like capire, finire, preferire, pulire add -isc- in all forms except noi and voi: capisco, capisci, capisce, capiamo, capite, capiscono. Strictly speaking these are regular-with-an-infix, but they trip up every beginner.

3. Hidden long infinitives

Fare, dire and bere are shortened forms of the older facere, dicere, bevere. Restore the long stem and the conjugation becomes obvious: faccio/facevo, dico/dicevo, bevo/bevevo. This single insight cleans up three high-frequency verbs at once.

4. Diphthong swaps

Stressed vowels break into diphthongs: venire → vieni, volere → vuoi, potere → può, uscire → esco. Unstressed forms revert (veniamo, volete, possiamo, usciamo).

5. Doubled-consonant future stems

Future and conditional share one stem, and the irregular ones are short and often doubled: essere → sarò/sarei, avere → avrò, andare → andrò, volere → vorrò, venire → verrò, bere → berrò, rimanere → rimarrò. Learn the stem once, get two tenses free.

6. The 1-3-3 passato remoto

In the historic past, most irregular verbs are irregular in exactly three slots — io, lui/lei and loro — and regular elsewhere: presi, prendesti, prese, prendemmo, prendeste, presero. Same for vidi/vedesti/vide, dissi/dicesti/disse, seppi/sapesti/seppe.

7. Truncated imperatives

Five verbs have apostrophised commands: va’ (or vai), da’, fa’, sta’, di’. Add a pronoun and the consonant doubles: dimmi (tell me), fammi (let me), dammi (give me), vattene (go away).

Irregular Past Participles You Cannot Avoid

The passato prossimo is where irregularity bites hardest, because a wrong participle is immediately audible. These are the ones worth drilling — note how many end in -tto, -sso or -sto.

Remember that participles taking essere must agree in gender and number: è venuta, siamo rimasti, sono andate. If you are still choosing auxiliaries by instinct, our breakdown of passato prossimo vs imperfetto covers the decision rule in detail.

How to Learn Them Faster: The Three-Slot Drill

Here is the method that consistently works in lessons, and it is deliberately unglamorous. Alphabetical verb lists fail because they group verbs that have nothing in common. Instead, drill by slot.

1. Pick one slot, not one verb. Take only the io form of ten irregular verbs and say them as a chain: vado, faccio, vengo, esco, tengo, scelgo, bevo, dico, posso, voglio. Your mouth learns the -go and -cc- shapes as a rhythm.
2. Add the mirror slot. Whatever the io stem is, loro almost always copies it: vado → vanno, vengo → vengono, tengo → tengono. Two forms for the price of one.
3. Attach a real sentence. Never store a form naked. Store esco alle otto, not esco. Retrieval in conversation happens through phrases, not tables.

Do this in five-minute blocks, out loud, daily. Twenty minutes of slot drilling beats two hours of reading conjugation charts, because irregularity is a motor-memory problem more than a knowledge problem. Pair it with input you enjoy — a podcast, a cooking video from an Italian channel, a novel — so the same verbs arrive from a second direction. For structure across all tenses, work alongside our Italian verb conjugation guide, and keep a running list of the forms you personally get wrong.

Common Mistakes English Speakers Make

• Overusing stare for “to be”. Stare covers location, health and progressive actions (sto bene, sto mangiando), not identity. Say sono stanco, not sto stanco.
• Regularising the participle. Ho prenduto and ho vedato are the classic slips. There is no shortcut here: participles are learned items.
• Forgetting the noi escape hatch. Learners freeze on io forms when andiamo would have been regular all along.
• Missing the accent on è and dà. E means “and”; da means “from”. The accent is not decoration.

For authoritative answers on usage disputes, the Accademia della Crusca publishes plain-language rulings from Italy’s official language body, and the Treccani dictionary lists full conjugations for every entry. Both are free, and both are what Italians themselves consult.

Frequently Asked Questions

How many irregular verbs are there in Italian?

Comprehensive references list several hundred, most of them second-conjugation verbs in -ere. In practice, around 20 verbs cover the vast majority of what you will say or hear in a normal day, and roughly 50 will carry you comfortably to B1. Learn those before worrying about the long tail.

Which Italian irregular verbs should I learn first?

Start with essere and avere, because they are also the auxiliaries for every compound tense. Then add fare, andare, stare, dare, venire, potere, volere and dovere. Those ten unlock introductions, plans, permission, obligation and the whole past tense.

Are Italian irregular verbs harder than Spanish or French ones?

They are broadly comparable to Spanish and considerably more transparent than French, mainly because Italian spelling matches pronunciation. The trade-off is that Italian has more irregular past participles, while French hides more irregularity in silent endings you cannot hear.

Do I need to learn the passato remoto?

For recognition, yes — it is standard in novels, history writing and much of southern Italian speech. For production, no. Most learners can recognise fu, ebbe, disse, fece and still use the passato prossimo when speaking. Focus your active effort on the present, passato prossimo, imperfect and future first, then browse our common Italian phrases for beginners to see these tenses in context.

The Bottom Line

Italian irregular verbs feel chaotic only until you sort them by pattern rather than by alphabet. Learn the ten highest-frequency verbs, recognise the seven families, drill by slot instead of by verb, and accept that irregular past participles are simply vocabulary. Six weeks of consistent, spoken practice will do more than any chart you print out and pin to the wall.
