What are prefixes in Italian?

Grammatically speaking, prefixes in Italian are small groups of letters added to the beginning of a word to create a new one. These tiny additions can completely change the meaning of the original word, making your Italian richer, more expressive, and a lot more fun to play with.

For example, adding a prefix can turn contento (happy) into scontento (unhappy, dissatisfied), or ordinario (ordinary) into straordinario (extraordinary). Same root, new meaning!

Unlike suffixes, prefixes don’t change the grammatical category of a word: a noun stays a noun, a verb stays a verb, and an adjective stays an adjective. The only thing that changes is the meaning. This way, you can grow your vocabulary without having to worry about other grammar rules.  

However, just like with suffixes, there are no strict rules for when to use one prefix over another with a particular word. The key is to practice and listen as much as possible. The good news? Many prefixes will sound familiar because they resemble English ones!

Below, you’ll find a list of some of the most common Italian prefixes. Of course, it’s not a complete list, and you’ll come across many more as you read books or binge-watch Italian TV series. But this selection is a great starting point for recognizing and using Italian prefixes naturally.

Italian prefixes for forming opposites

1. Italian Prefix: S-

The prefix s- is one of the most common ways to form opposites in Italian. When added to a word, it gives it the opposite meaning of the original base word. 

Some examples:

Here are some example sentences:

• Carichiamo tutte le valigie in macchina e poi scarichiamo solo quelle che ci servono  alla prima tappa del viaggio. – Let’s load all the suitcases into the car, and then we only unload the ones we need at the first stop.
• Se leghi le scarpe troppo strette, poi devi slegarle perché ti fanno male! – If you tie your shoes too tight, you’ll have to untie them because they hurt!

2. Italian Prefix: Dis-

The Italian prefix dis- is used to express the opposite meaning of a word or to describe something that is lacking or not functioning properly compared to what the base word expresses. It’s particularly common in medical terminology to signal that something in the body isn’t functioning as it should.

Some examples:

Here are some example sentences:

• La riabilitazione mira a recuperare le abilità motorie perse a causa della disabilità. – The rehabilitation aims to restore motor skills lost due to disability.
• Mia sorella è molto ordinata, mentre io sono piuttosto disordinata. – My sister is very tidy, while I’m quite messy.

3. Italian Prefix: In-

In- is another useful prefix in Italian to create the opposite of a word: it basically negates its original meaning.

Some examples:

Here is an example sentence:

• È giusto aiutare chi ha bisogno, ma è ingiusto approfittarsi della gentilezza degli altri. – It’s right to help those in need, but it’s unfair to take advantage of others’ kindness.

However, in- changes its form slightly depending on the first letter of the word it’s added to to make pronunciation smoother in Italian:

Before m, b, p, in- becomes im-

Here is an example sentence:

• Non è possibile pensare che sia impossibile cambiare. – It’s not possible to think that it’s impossible to change.

Before L, in- becomes il-

Here is an example sentence:

• L’avvocato ha spiegato che l’attività era perfettamente legale, ma alcuni clienti agivano in modo illegale. – The lawyer explained that the business was perfectly legal, but some clients were acting illegally.

Before r, in- becomes ir-

Here is an example sentence:

• In italiano ci sono molti verbi regolari, ma anche alcuni irregolari che bisogna memorizzare. – In Italian there are many regular verbs, but also some irregular ones that you need to memorize.

4. Italian Prefix: A-

When you add the prefix a- to a word, you’re usually saying that something doesn’t have the quality or characteristic expressed by the root word.

Some examples:

Here is an example sentence:

• È tipico che faccia caldo a giugno, ma quest’anno è davvero atipico: serve la giacca! – It’s typical for it to be hot in June, but this year is really unusual: you need a jacket!

If the base word starts with a vowel, the prefix a- becomes an- to make the pronunciation more fluid, such as:

Here is an example sentence:

• Io ho ordinato un cocktail analcolico, mentre il mio amico ne ha scelto uno alcolico. – I got a non-alcoholic cocktail, and my friend went for an alcoholic one.

Italian prefixes for building opposite meanings 

5. Italian Prefix: Anti-

The prefix anti- expresses the idea of preventing something, or that something comes before or stands in front of something else.

Some examples:

Here are some example sentences:

• In estate qui ci sono molte zanzare, quindi uso sempre lo spray antizanzare. – There are tons of mosquitoes here in the summer, so I always use mosquito repellent.
• La camera è moderna, ma l’anticamera sembra uscita dagli anni ’80! – The room is modern, but the anteroom looks like it’s from the 1980s!

6. Italian Prefix: Contro-

When added to a word, contro- indicates that something goes against or acts in the opposite direction of what the base word expresses.

Some examples:

Here are some example sentences:

• La luce diretta illumina le figure, mentre il controluce ne evidenzia i contorni. – Direct light illuminates the figures, while backlighting highlights their contours.
• La parte lesa ha chiesto un risarcimento alla controparte. – The injured party demanded compensation from the opposing party.

Italian prefixes for expressing position in place or time

7. Italian Prefix: Pre-

The Italian prefix pre- refers to something that happens earlier in time or, less often, before something else in space or order. So, when you see pre- at the start of a word, it usually tells you that the action or thing happens or comes before something else.

Some examples:

Here is an example sentence:Here are some example sentences:

• Posso pagare alla consegna o devo prepagare online? – Can I pay on delivery or do I have to prepay online?
• Premetto che non voglio criticare, ma devo mettere alcuni puntini sulle i! – I don’t want to criticize, but I need to set a few things straight!

8. Italian Prefix: Sopra- / Sovra-

Both sopra- and sovra- come from the idea of being above something, either physically or figuratively (in Italian, sopra is also a common preposition of place). They can suggest superiority, excess, or going beyond normal limits. The main difference is in tone and context:

Sopra- is more common in everyday language, and means being physically above or on top of something.

Here are some example sentences:

• Il suo nome è Alessandro, ma tutti lo chiamano con il soprannome “Lallo.” – His name is Alessandro, but everyone calls him by the nickname “Lallo.”
• Sul mobile del salotto c’è un soprammobile che mi ha regalato mia nonna. – On the living room cabinet there’s an ornament my grandmother gave me.

Sovra- is more formal, used especially in academic or technical Italian, and often means “beyond” or “superior to.” 

Here are some example sentences:

• La mia giornata è già carica di cose da fare, non voglio sovraccaricarla di altri impegni. – My day is already full of things to do — I don’t want to overload it with more commitments.
• Scrivere sul database è un’operazione delicata: se si sovrascrive un campo per errore, si possono perdere dati importanti. – Writing to the database is a delicate operation: if you overwrite a field by mistake, you can lose important data.

Spelling notes: 

• When sopra-/sovra- is followed by a word beginning with a consonant, that consonant is often doubled, like carico (load)- sovraccarico (overload).
• When the base word begins with a vowel, that vowel is often dropped, as in abito (dress) – soprabito (overcoat).

9. Italian Prefix: Sotto-

In addition to being an adverb of place, sotto- is also a prefix that means “under.” It can refer to something being physically beneath something else or metaphorically below in rank, importance, or level.

Some examples:

Here are some example sentences:

• Non appoggiare i bicchieri senza i sottobicchieri, altrimenti il tavolo si rovina! – Don’t set the glasses down without coasters, or the table will get damaged!
• Non voglio stare in un posto dove devo sottostare a regole assurde. – I don’t want to stay in a place where I have to submit to absurd rules.

10. Italian Prefix: Sub-

The prefix sub- is very similar to sotto-, and both convey the idea of something being under, below, or less than something else. You’ll often see sub- used when something is physically underneath, a smaller or secondary part of something bigger, or just lower in rank or importance.

Some examples:

Here are some example sentences:

• Il conscio elabora le informazioni razionalmente, mentre il subconscio lavora in modo più istintivo. – The conscious mind processes information rationally, while the subconscious works more instinctively.
• Le autorità stanno stanno pianificando un nuovo sistema di trasporti per collegare meglio le zone urbane e suburbane. – Authorities are planning a new transportation system to better connect urban and suburban zones.

Italian prefixes for expressing intensity 

11. Italian Prefix: Stra-

The prefix stra- in Italian adds the idea of something extreme, exaggerated, or “extra.” So whenever you see stra- at the beginning of a word, it means “very,” “super,” or “extremely.”

Some examples:

Here are some example sentences:

• Il pollo era cotto a puntino, ma la pasta era stracotta. – The chicken was cooked to perfection, but the pasta was overcooked.
• Vai a fare due passi, ma senza strafare: sei ancora debole. – Go for a short walk, but don’t overdo it: you’re still weak.

The prefix stra- is super popular in informal and slang expressions, for instance:

Here are some example sentences:

• Il gelato di ieri era buono, ma questo è strabuono! – Yesterday’s ice cream was good, but this one is super good!
• Il compito in classe è andato bene, anzi direi strabene! – The test went well, actually, super well!

12. Italian Prefix: Iper-

The prefix -iper is used to show that something is in a higher or exaggerated degree.
So, when you add iper- to a word, you’re saying that something goes beyond the usual or is too much of something.

Some examples:

Here are some example sentences:

• Ho la pelle sensibile, ma in inverno diventa addirittura ipersensibile al freddo. – I have sensitive skin, but in winter it becomes downright hypersensitive to the cold.
• Ormai in città ci sono più ipermercati che mercati rionali. – These days, there are more hypermarkets/superstores than local markets in the city.

Italian prefixes denoting repetition and association

13. Italian Prefix: Re- / Ri-

The prefixes re- and ri- add the idea of doing something again. In some words, they can also show a return to an earlier condition or point, not just repetition.

Some examples:

Here are some example sentences:

• Prova e riprova, alla fine sono riuscita a risolvere il problema. – By trying again and again, I finally managed to solve the problem.
• Oggi non basta inventare qualcosa di nuovo: bisogna anche saperlo reinventare nel tempo. – These days, it’s not enough to invent something new; you also have to know how to reinvent it over time.

14. Italian Prefix: Bi- / Bis-

The prefixes bi- and bis- are used when something involves two parts, two sides, or happens twice.

Some examples:

Here are some example sentences:

• In soffitta abbiamo trovato vecchie foto dei nostri nonni e persino dei nostri bisnonni. – In the attic we found old photos of our grandparents and even of our great-grandparents.
• L’associazione ha organizzato una mostra speciale in occasione del centenario dell’artista e del bicentenario del museo che ospita I suoi quadri. – The association organized a special exhibition to mark the 100th anniversary of the artist’s birth and the 200th anniversary of the museum that’s hosting his paintings.

Attenzione: In some words, the prefix bis- can take on a more informal, slightly negative meaning, suggesting that something feels odd or not quite right. For instance:

Here is an example sentence:

• Lui la tratta da regina e lei non fa altro che bistrattarlo. – He treats her like a queen, and she just keeps mistreating him. 

15. Italian Prefix: Con-

Con- means “with” or “together,” adding to the word a sense of doing something together, sharing an action, or being connected with others.

Some examples:

Here is an example sentence:

• Vivere un amore è meraviglioso, ma convivere richiede tanta pazienza! – Experiencing a love story is wonderful, but living together requires so much patience!

The prefix con- changes form depending on the letter that follows it, just to make pronunciation smoother.

Before m, b, p, con- becomes com-, like:

Here is an example sentence:

• Anche se è proprietaria della casa, deve chiedere il consenso del comproprietario per venderla. – Even though she’s the owner of the house, she must ask the co-owner’s permission to sell it.

Before l or r, con- becomes col- or cor- respectively, like:

Here is an example sentence:

• Il capo progetto è responsabile della pianificazione, ma l’intero gruppo è corresponsabile dell’esecuzione. – The project leader is responsible for planning, but the entire group is co-responsible for execution.

Before a vowel, con- becomes co-, such as:

Here is an example sentence:

• Sergio è autore del brano musicale e coautore del testo della canzone. – Sergio is the author of the music and the co-author of the song’s lyrics.
