Noun-forming suffixes (-zione, -mento, -ezza, -ità)

Learning a few key suffixes lets you rapidly expand your vocabulary. By transforming words you already know (like verbs and adjectives) into abstract nouns, you can instantly unlock hundreds of new concepts.

Actions into Concepts: -zione

To turn a verb into an abstract noun, Italian frequently uses the suffix -zione. These nouns are always feminine and equivalent to English words ending in "-tion". For example, spiegare (to explain) becomes la spiegazione (explanation), and prenotare (to reserve) becomes la prenotazione (reservation).

The explanation of this rule is very difficult.
La spiegazione di questa regola è molto difficile.
I want an explanation about the reservation by tomorrow.
Voglio una spiegazione sulla prenotazione entro domani.

Processes and Results: -mento

Another common verb-to-noun suffix is -mento. These nouns are always masculine and usually correspond to English nouns ending in "-ment" or gerunds ending in "-ing". For example, funzionare (to function) becomes il funzionamento (functioning), and migliorare (to improve) becomes il miglioramento (improvement).

Its functioning is terrible, we must improve it.
Il suo funzionamento è pessimo, dobbiamo migliorarlo.

You can easily mix these suffixes to discuss processes and their outcomes:

The description shows an evident improvement.
La descrizione mostra un evidente miglioramento.

Qualities and States: -ezza

To turn an adjective into a noun describing a quality, use -ezza. These nouns are always feminine and act like the English suffix "-ness". For example, bello (beautiful) becomes la bellezza (beauty), and debole (weak) becomes la debolezza (weakness).

The beauty of this poem hides a great sadness.
La bellezza di questo poema nasconde una grande tristezza.
His weakness is chocolate.
La sua debolezza è il cioccolato.

Characteristics: -ità

The suffix -ità turns adjectives into feminine abstract nouns, corresponding to the English suffix "-ity". Because they end in an accented vowel, they are invariable (their endings do not change in the plural). For instance, comodo (comfortable/convenient) becomes la comodità (convenience), and nuovo (new) becomes la novità (novelty).

Convenience is more important than time.
La comodità è più importante del tempo.

Now that you've learned all four suffixes, you can comfortably weave multiple abstract concepts together in a single sentence:

I see the connection between the sadness and the novelty.
Vedo il collegamento tra la tristezza e la novità.
