Adjective Suffix -bile
The suffix -bile is the Italian equivalent of the English -able or -ible. It transforms verbs into adjectives that describe possibility or potentiality.
How It Works
The suffix -bile is a highly productive tool in Italian used to create adjectives from verbs. It generally carries three main nuances:
- Passive Nuance: With transitive verbs, it means 'that can be [verb]ed'. For example, lavabile (washable/can be washed).
- Active Nuance: With intransitive verbs, it describes a quality of the subject. For example, deperibile (perishable/that can spoil).
- Worthiness: It can indicate that something is 'deserving of' an action. For example, mirabile (admirable/worthy of wonder) or laudabile (praiseworthy).
Morphology and Pronunciation:
1. -are verbs: Use the thematic vowel 'a' → -abile (e.g., amare → amabile).
2. -ere and -ire verbs: Use the thematic vowel 'i' → -ibile (e.g., leggere → leggibile; udire → udibile).
3. Stress and Plurals: These adjectives are parole sdrucciole, meaning the stress falls on the antepenultimate syllable (the thematic vowel 'a' or 'i'), such as la-VÀ-bi-le or leg-GÌ-bi-le. They follow the pattern of nouns/adjectives ending in -e, meaning the plural form always ends in -bili (e.g., invisibile → invisibili).
Negative Prefixes:
Adjectives in -bile are very frequently paired with negative prefixes to express the opposite meaning:
- in- + visibile → invisibile (invisible)
- il- + leggibile → illeggibile (illegible)
- in- + dicibile → indicibile (unspeakable/indescribable - note that dicibile is rarely used alone).
Irregular Stems:
Some verbs use a modified stem based on Latin roots:
- Fare → fattibile (feasible)
- Vedere → visibile (visible)
- Bere → bevibile (drinkable)
Examples (5)
- Questa maglia è lavabile in lavatrice.

- Il testo non è leggibile perché la scrittura è troppo piccola.
The text is not readable because the handwriting is too small.
Word by Word: The text not is readable because the writing is too small.
The adjective 'leggibile' comes from the -ere verb 'leggere' (to read).
- È un progetto difficile, ma assolutamente fattibile.
It is a difficult project, but absolutely feasible.
Word by Word: It is a project difficult, but absolutely doable.
'Fattibile' is an irregular form derived from the verb 'fare' (to do/make).
- I cibi deperibili devono stare in frigo.
Perishable foods must stay in the fridge.
Word by Word: The foods perishable must stay in fridge.
'Deperibile' comes from 'deperire' (to perish) and shows the active nuance of the suffix.
- La tua proposta è accettabile per noi.
Your proposal is acceptable to us.
Word by Word: The your proposal is acceptable for us.
'Accettabile' comes from 'accettare' (to accept).
Common Mistakes
Using the wrong thematic vowel (using -abile for all verbs).
Il carattere è leggabile.Il carattere è leggibile.Since 'leggere' is an -ere verb, it must use the -ibile ending, not -abile.
Attaching the suffix to the full infinitive instead of the stem.
È un film guardarebile.È un film guardabile.You must drop the -are/-ere/-ire ending before adding -bile.
Using -evole where the meaning is 'can be done'.
Questa maglia è lavevole in lavatrice.Questa maglia è lavabile in lavatrice.Use -bile for something that can be done to a thing (lavabile = can be washed). -evole names a quality or tendency, as in amorevole (affectionate). Amabile and amorevole are both real words with different meanings, and 'lavevole' does not exist.
How It Connects
