Italian Verb-Forming Suffixes

If you want to invent an Italian verb today — from a noun, an adjective, an English borrowing, even a brand name — you have one default move and three specialised tools. The default is -are: just bolt it on the end of any root and you have a working verb. Chat → chattare, Google → googlare, email → emailare (informal). The specialised tools are -eggiare (older Italian, "to behave/act like X"), -izzare (modern, technical, "to make X-like"), and -ificare (slightly formal, "to make X"). Together these four patterns account for essentially every verb coined in Italian in the last two centuries.

This page is the systematic reference. It explains why -ARE absorbs nearly all new vocabulary, when each specialised suffix is preferred, and how the resulting verbs join the broader Italian word-formation system to spawn their own families of nouns and adjectives. For the broader picture, see Word Formation: Overview and Verb Classes and Productivity.

1. -are: the default productive class

The -ARE class is the workhorse. Modern Italian neologisms join -ARE almost without exception. The pattern is simple: take the noun or adjective, attach -are, and you have an infinitive. Some adjustments may apply to the stem (epenthetic vowels, consonant simplifications), but the basic pattern is mechanical.

Common types

From nouns (denominal verbs):

From adjectives (deadjectival verbs):

From English/foreign borrowings (the productive modern category):

Why -ARE wins

Three reasons:

1. Phonological convenience: any consonant cluster + -are is pronounceable. The -ERE and -IRE classes have stricter morphological constraints (often requiring a specific stem shape).
2. Inheritance from Latin: -ARE descends from Latin first-conjugation verbs (amare → amare), which was already the productive class in Late Latin. This pattern was preserved.
3. Network effects: as -ARE became the productive class, speakers came to expect it for new verbs, and this expectation reinforced itself.

Conjugation: the rewards of -ARE

Joining -ARE has a side benefit: -ARE verbs are morphologically the simplest. The 1sg present is -o (chatto, telefono); the past participle is -ato (chattato, telefonato); the gerund is -ando (chattando); the imperfect is -avo (chattavo). No mood-specific stem changes, no tricky past participles. Newcomers to the language can use a brand-new -ARE verb confidently in any tense after about two minutes' practice.

2. -eggiare: behave like, act in the manner of

A specialised verb-forming suffix from older Italian (perhaps from Latin -igare via Old French -eier). The semantic core: to act like the noun or adjective, to behave characteristically, often with a sense of gradual or characteristic action.

Common patterns

The semantic flavor of -eggiare

This suffix often carries a gradual or characteristic sense — not a single completed action but a state of being or acting:

• Lampeggiare is not "to flash once" but "to be flashing" (lightning in the distance, a turn signal continuing to blink).
• Rosseggiare is not "to turn red instantly" but "to be in the process of looking red, gradually appearing red."
• Signoreggiare is "to lord over, to be dominantly present," not "to assume lordship in a moment."

For learners, -eggiare verbs frequently show up in literary or older registers, in nature description, and in describing characteristic behavior. They are still produced, but somewhat less productively than -izzare in modern technical vocabulary.

Productivity

Moderate. New -eggiare verbs are coined occasionally, often with a slightly old-fashioned or literary feel. Modaiolo → modaioleggiare (to act in a fashionable / fashion-y way) is recent. But for new technical or abstract vocabulary, modern Italian usually prefers -izzare.

3. -izzare: standardize, formalize, technicalize

The modern, productive, technical verb-forming suffix. From Greek -izō via Latin -izare (and English/French equivalents -ize / -ise / -iser). The semantic core: to make X-like, to standardize, to bring under a system named by the source noun or adjective.

Common patterns

The semantic flavor of -izzare

This suffix is modern, technical, and abstract. It belongs to:

• Scientific and technical vocabulary: sintetizzare, polimerizzare, normalizzare, standardizzare, ottimizzare.
• Political and social vocabulary: democratizzare, privatizzare, nazionalizzare, secolarizzare, polarizzare.
• Computing and tech vocabulary: computerizzare, digitalizzare, virtualizzare, automatizzare, ottimizzare.

The connotation is somewhat clinical or institutional — not warm or characterful (the way -eggiare can be), but precise, abstract, and often slightly distancing.

Productivity: very high

The most productive specialized verb-forming suffix in modern Italian. Essentially every neologism in technical, political, or social discourse uses -izzare. Tokenizzare (in NLP), containerizzare (in IT), rebrandizzare (in marketing) are all working examples.

-izzare vs -eggiare: the same root, different verbs

For some roots, both forms exist, and they differ in nuance:

Rule of thumb: when both exist, -eggiare is usually older, more literary, and slightly characterful (often with a gradual or characteristic sense); -izzare is modern, technical, and abstract.

4. -ificare: to make X (slightly formal)

A third specialised suffix, from Latin -ificare (verb-forming compound of -i + facere). Semantic core: to make X, the causative of being something. Closely parallel to English -ify.

Common patterns

The semantic flavor of -ificare

Formal, causative, often slightly clinical. -ificare verbs feel:

• More formal than -izzare in everyday register.
• More causative than -izzare (which leans toward "make X-like" rather than "literally make X").
• Often technical or legal: certificare, qualificare, identificare, verificare are all in formal register.

Productivity

Lower than -izzare, but moderate. New coinings exist: gamificare (to gamify, from English gamify), desertificare (to desertify, environmental term). The suffix is alive but conservative.

-ificare vs -izzare: comparison

For some roots, both exist:

For most modern technical neologisms, -izzare is the default choice. -ificare survives in lexicalized forms (verificare, classificare, modificare, identificare, qualificare) and is occasionally extended to new roots, especially when the meaning is "literally make X" (gamificare = literally make-into-a-game).

5. The minor patterns: -care, -gare, -ire

A few smaller patterns deserve mention.

-care, -gare: spelling-driven variants of -are

These are not separate suffixes but spelling adjustments of -are when the root ends in /k/ or /g/. Pizzicare (to pinch) ends in -care because the root pizzico ends in /k/, and Italian orthography uses c before a. The verb conjugates with -h- to keep the /k/ sound: pizzichi, pizzichiamo (not pizzici, pizziciamo).

-ire (with -isc- extension): a small productive corner

The -IRE class is mostly closed, but it does accept new entries via the -isc- extension pattern: finire (to finish, finisco, finisci, finisce), capire (to understand), preferire, spedire. These are not currently coined freely from new roots — but they form a stable productive subclass, especially for verbs derived from adjectives with a "becoming" or "making X" sense.

Latin/Greek learned compounds

Italian also imports learned compound verbs directly from Latin and Greek, like telecomunicare, autodichiararsi, fotografare, cinetelevisare (rare). These are more compounds than suffixed forms; they usually still join -ARE.

6. Derivation chains: from verb to family

The verb-forming suffixes do not work in isolation. Once a noun or adjective becomes a verb, that verb can spawn its own family of nouns and adjectives. Watch one root produce a whole family:

il problema (the problem) → problematizzare (to problematize)

• il problema (root noun)
• problematico, problematica (adjective: problematic)
• la problematica (noun, abstract: the issue, the problem at large)
• problematizzare (verb: to problematize, to render problematic — academic/critical)
• la problematizzazione (action noun: the problematization)
• il problematizzatore / la problematizzatrice (agent: one who problematizes — rare)

il fiore (the flower) → fiorire (to flower / bloom — irregular -IRE)

• il fiore (root noun)
• fiorire (verb, -IRE class with -isc-: to flower, to bloom)
• fiorito, fiorita (past participle as adjective: in bloom)
• la fioritura (action/result noun: the blooming, the flowering)
• il fiorista / la fiorista (occupational noun: florist, gender-neutral)
• fioraio / fioraia (older form for florist: less common today)

la classe (the class) → classificare (to classify)

• la classe (root noun)
• classico, classica (adjective: classical)
• classificare (verb: to classify)
• la classificazione (action noun: classification)
• il classificatore / la classificatrice (agent: classifier, often the physical filing cabinet)
• classificato, classificata (past participle as adjective: classified)

7. Productivity summary

A reference table for which patterns to use when coining or reading new verbs.

Decision rule for new verbs:

1. If the verb is from a noun, adjective, or borrowing with a general sense ("to do X-thing") → -are.
2. If the verb is technical, abstract, or institutional ("to formalize, to digitalize") → -izzare.
3. If the verb is causative and slightly formal ("to verify, to gamify") → -ificare.
4. If the verb is older Italian or literary with a "behave like" sense → -eggiare.

Common Mistakes

Mistakes English speakers make with Italian verb-forming suffixes:

Key takeaways

1. The -ARE class is the open verb class. Almost every new Italian verb — borrowed from English, derived from a noun or adjective, or coined for a new technology — joins -ARE. Chattare, googlare, downloadare, telefonare all follow this pattern. The -ERE class is essentially closed; the -IRE class accepts only a small productive corner with the -isc- extension.

2. -eggiare is the older Italian "behave like / act in the manner of" suffix. Lampeggiare, festeggiare, parteggiare, rosseggiare. It often carries a gradual or characteristic sense and is moderately productive in older or literary register.

3. -izzare is the modern technical/abstract suffix. Modernizzare, digitalizzare, formalizzare, sintetizzare, realizzare. Highly productive in scientific, political, and computing vocabulary; the modern preference for new institutional verbs.

4. -ificare is the slightly formal causative suffix. Verificare, classificare, modificare, specificare, gamificare. Moderately productive, often in formal/legal/technical contexts.

5. The choice between -izzare and -eggiare for the same root tracks register: -izzare is modern/technical, -eggiare is older/characterful. Computerizzare (technical) ≠ computereggiare (rare, dismissive).

6. Verb-forming suffixes feed into noun-forming suffixes to spawn whole word families. Realizzare → realizzazione, realizzato, realizzatore. Mastery of both verb and noun suffix systems is what makes Italian vocabulary feel decodable.

7. For learners: when in doubt, default to -are. It is the safest, most productive, and most morphologically transparent pattern. The specialised suffixes (-eggiare, -izzare, -ificare) are for recognition; you can produce mostly with -are and sound natural in modern Italian.
