Regular -IRE Verbs in Italian

In Brief

For regular -ire verbs without -isc-, remove -ire from the infinitive and add -o, -i, -e, -iamo, -ite, -ono. Thus dormire becomes dormo, dormi, dorme, dormiamo, dormite, dormono. Not every verb ending in -ire follows this pattern: verbs such as finire use the separate -isc- pattern in some persons.

Overview

Italian dictionaries list verbs in the infinitive, the basic unconjugated form corresponding to English “to sleep,” “to leave,” or “to open.” Infinitives ending in -ire belong to the third Italian conjugation, or verb family. This article focuses on regular members of that family that do not insert -isc- in the present tense: dormire (to sleep), partire (to leave), sentire (to hear or feel), and aprire (to open).

This is an A1 pattern and one of the foundations of everyday Italian. You need it to say when you leave, how much you sleep, what you hear, and when places open. Unlike English, which often keeps the verb unchanged (I sleep, we sleep, they sleep), Italian gives each grammatical person—the speaker, the listener, or someone else, singular or plural—its own ending.

Those distinctive endings also explain why Italian often leaves out subject pronouns. Partiamo alle otto already means “We leave at eight”: the ending -iamo identifies noi (we). State the pronoun when it adds emphasis or contrast, not simply because English requires one.

How It Works

Build the present tense

Start with the infinitive, remove its final -ire, and keep the remaining stem (the part that carries the verb’s main meaning). Then attach the present-tense ending.

• dormire → dorm- → dormo
• partire → part- → partite
• sentire → sent- → sentono
• aprire → apr- → apriamo

The complete pattern is:

Person	Subject pronoun	Ending	dormire	Basic meaning
1st person singular	io	-o	dormo	I sleep / I am sleeping
2nd person singular	tu	-i	dormi	you sleep / you are sleeping
3rd person singular	lui, lei, Lei	-e	dorme	he/she sleeps; you sleep (formal)
1st person plural	noi	-iamo	dormiamo	we sleep / we are sleeping
2nd person plural	voi	-ite	dormite	you all sleep / are sleeping
3rd person plural	loro	-ono	dormono	they sleep / are sleeping

The same endings attach to the other regular stems:

Person	partire	sentire	aprire
io	parto	sento	apro
tu	parti	senti	apri
lui/lei/Lei	parte	sente	apre
noi	partiamo	sentiamo	apriamo
voi	partite	sentite	aprite
loro	partono	sentono	aprono

Notice two especially useful clues: -iamo always marks noi in this pattern, while -ite marks voi. The singular forms are short, so learn them as complete spoken units: parto, parti, parte.

Statements, negatives, and questions

Italian does not need an extra verb equivalent to English do/does in present-tense questions and negatives.

Function	Pattern	Example	Meaning
statement	conjugated verb + rest	Parti domani.	You leave tomorrow.
negative	non + conjugated verb	Non parti domani.	You are not leaving tomorrow.
question	question intonation or question phrase	Parti domani?	Are you leaving tomorrow?
information question	question phrase + conjugated verb	Quando partite?	When are you leaving?

In writing, the question mark signals a question. In speech, intonation and context do the work; Italian normally does not invert the subject and verb in the English way.

Subject pronouns and formal address

You can say io dormo, but plain dormo is usually enough. Include a pronoun to correct, compare, or emphasize:

• Io parto, ma loro restano. — “I’m leaving, but they are staying.”
• Tu apri il negozio o lo apre Marta? — “Are you opening the shop, or is Marta opening it?”

Formal singular Lei uses the same third-person singular form as lei (she): Lei parte, Lei sente, Lei apre. Capitalizing Lei is common when it clearly means formal “you,” especially in careful writing, though lowercase is also encountered.

The present tense has several English equivalents

Italian’s presente indicativo (the ordinary present used for facts, habits, and current events) can correspond to both the English simple present and present continuous:

• Dormo poco. — “I sleep little.”
• Adesso dorme. — “He/She is sleeping now.”

Italian can use stare plus a gerund to stress an action in progress (sta dormendo), but it does not need that construction every time English uses “is sleeping.” The simple present is often natural when words such as adesso make the timing clear.

Recognizing the two -IRE patterns

The infinitive alone does not reliably tell you whether an -ire verb takes these endings directly or inserts -isc-. Compare:

Person	non-isc: dormire	-isc- verb: finire
io	dormo	finisco
tu	dormi	finisci
lui/lei	dorme	finisce
noi	dormiamo	finiamo
voi	dormite	finite
loro	dormono	finiscono

Both groups have -iamo and -ite in the noi and voi forms. Learn a new -ire verb with its io form—dormire, dormo but finire, finisco—instead of guessing from the infinitive.

Examples in Context

Italian	English	Note
Dormo otto ore.	I sleep eight hours.	Habit; io is understood.
Dormi già?	Are you sleeping already?	A question needs no equivalent of “do.”
Il bambino dorme.	The child is sleeping.	Third-person singular.
Nel fine settimana dormiamo fino a tardi.	At the weekend, we sleep late.	-iamo identifies “we.”
A che ora parti?	What time are you leaving?	A planned event expressed in the present.
Partiamo da Milano alle sette.	We leave Milan at seven.	Partire da gives the departure point.
Signora, parte oggi?	Are you leaving today, ma’am?	Formal singular; understood Lei.
I treni partono ogni mezz’ora.	The trains leave every half hour.	Plural subject and -ono.
Sentiamo la musica dalla strada.	We can hear the music from the street.	English may naturally add “can.”
Non sento bene.	I can’t hear well.	Non goes directly before the verb.
Senti freddo?	Do you feel cold?	Sentire can concern bodily sensation.
Apro la finestra perché fa caldo.	I’m opening the window because it’s hot.	Present action.
A che ora aprite il ristorante?	What time do you open the restaurant?	voi can address several people or a business staff member.
I musei aprono alle nove.	The museums open at nine.	Timetable or regular schedule.

Common Mistakes

Adding -isc- to every -IRE verb

• Wrong: Io dormisco otto ore.
• Right: Io dormo otto ore.
• Why: Dormire belongs to the group that adds the endings directly to dorm-. The existence of finisco does not make -isc- a general -ire ending.

Using an English-style unchanged verb

• Wrong: Noi dorme fino alle nove.
• Right: Noi dormiamo fino alle nove.
• Why: The ending must agree with the subject. Noi requires -iamo; dorme belongs to lui, lei, or formal Lei.

Choosing the wrong third-person ending

• Wrong: I negozi apre alle dieci.
• Right: I negozi aprono alle dieci.
• Why: I negozi is plural, so use third-person plural aprono. Singular il negozio takes apre.

Inserting “do” into a question

• Wrong: Fai tu parti domani?
• Right: Parti domani?
• Why: A present-tense Italian question normally uses the same verb form as a statement, with question intonation. Fare is not used as an auxiliary matching English “do.”

Keeping the subject pronoun in every sentence

• Awkward in neutral context: Io parto alle otto. Io apro l’ufficio. Io sento il telefono.
• More natural: Parto alle otto. Apro l’ufficio. Sento il telefono.
• Why: Italian verb endings normally make the subject clear. Repeated io can sound overly emphatic or contrastive.

Guessing the pattern from the ending alone

• Wrong: assuming capire behaves like partire: capo, capi, cape.
• Right: capisco, capisci, capisce.
• Why: Some -ire verbs use -isc- and must be learned as a separate subgroup. Record the io form when learning vocabulary.

Usage Notes

Useful meanings and prepositions

A conjugation may be regular while the verb’s use still differs from English. Partire often combines with da for a point of departure and per for a destination: Parto da Roma per Napoli (“I leave Rome for Naples”). It can also appear without either when the context is obvious: Partiamo domani.

Sentire covers more than English “hear.” Depending on what follows, it can mean “hear,” “feel,” “smell,” or “sense”: sento un rumore (I hear a noise), sento freddo (I feel cold), sento odore di caffè (I smell coffee). It can also mean “speak to/hear from” someone, especially in Ci sentiamo domani (“We’ll speak tomorrow” or “Talk to you tomorrow”). Context chooses the natural English translation.

Schedules and the near future

The present tense commonly describes a scheduled or settled future event: Il treno parte alle 18:10 or Partiamo venerdì. English does this too (“The train leaves at 6:10”), although English often prefers “we’re leaving” for a personal arrangement. A time expression usually makes the future meaning unambiguous.

Pronunciation and stress

The written endings are stable, but stress is worth hearing and copying. In dormiamo and dormite, the stress falls on the ending: dor-MIA-mo, dor-MI-te. In dormono, it moves back: DOR-mo-no. Listening to complete forms helps prevent a mechanically pronounced paradigm.

Beyond the Basics

You do not need to master the following forms at A1, but they show how the same verbs behave in later grammar.

The regular infinitive family does not guarantee that every other form is regular. The past participle (a form used with an auxiliary verb to build compound tenses) usually ends in -ito for this group: dormito, partito, sentito. However, aprire has the irregular participle aperto, not aprito. In the past, verbs also choose different auxiliaries: ho dormito (“I slept”), ho sentito (“I heard”), and ho aperto (“I opened”), but sono partito/partita (“I left”). That auxiliary choice is a separate topic and should be learned with each verb.

The gerund (the verb form used in a progressive construction, like English “-ing”) is regularly formed with -endo: dormendo, partendo, sentendo, aprendo. This gives forms such as Sto dormendo (“I’m sleeping”). Do not confuse -endo with the ordinary present tense: Dormo may already mean “I’m sleeping,” while sto dormendo places extra focus on the action in progress.

Several common related forms add pronouns to the verb and may shift the meaning. Sentirsi means “to feel” in expressions about one’s condition: Mi sento bene (“I feel well”). Aprirsi can mean “to open” without a stated agent: La porta si apre (“The door opens”). These are reflexive or pronominal constructions—verbs used with small pronoun words such as mi or si—and deserve separate study.

Finally, modern usage is the best guide to a verb’s pattern. The distinction between plain -ire and -isc- is lexical: it belongs to the individual verb, not to a broad difference in meaning. A dictionary that supplies io or a conjugation table resolves uncertainty quickly.

Practice Tips

1. Drill endings with contrasts. Say one stem through all six forms—parto, parti, parte, partiamo, partite, partono—then make short pairs such as parto/partono and apre/aprono. This trains both person and number.
2. Learn each verb as a small package. Record the infinitive, the io form, and one useful phrase: sentire — sento — Non sento bene. The io form immediately reveals whether an -ire verb uses -isc-.
3. Turn daily routines into questions and negatives. Change Dormite otto ore into Dormite otto ore? and Non dormite otto ore. You practise the conjugation while learning that Italian needs neither English-style inversion nor auxiliary “do.”
