The -ISC verbs

The -ISC conjugation pattern is a subset of the Italian 3rd conjugation (-ire). This subset of verbs, such as finire, capire, and pulire, add “-isc” in the present tense for the first, second, third persons singular, and third person plural. The “noi” and “voi” forms do not use “-isc”. Luckly, there are not many verbs that follow these conjugation pattern.

Pronunciation Rule

The first person singular (io capisco – I understand) and third person plural (loro capiscono) have a hard sound in the combination ‘sc,’ which should be pronounced like “skateboard.”

Instead, the second and third person singular (tu capisci – you understand / lui capisce – he understands) should be pronounced as in “shoot.

Iocapisc-o‘sk’ as in “skateboard”
Tucapisc-i‘ch’ as in “shoot”
Lui/Leicapisc-e‘ch’ as in “shoot”
Noicapiam-o‘sk’ as in “skateboard”
Voicapite‘sk’ as in “skateboard”
Lorocapisc-ono‘sk’ as in “skateboard”

most common -isc- verbs in Italian

Is there any way to determine when to use the -isc- conjugation?

Unfortunately, there is no strict rule, but rather a trend. Verbs whose fifth-to-last letter in the infinitive is a vowel tend to use the -isc- conjugation, though this is not always true.

Examples include:

  • Finire (to finish)
  • Pulire (to clean)
  • Spedire (to ship)
  • Proibire (to prohibit)

However, if the fifth-to-last letter in the infinitive happens to be a consonant, the verb follows the regular conjugation.

Examples include:

  • Aprire (to open)
  • Dormire (to sleep)
  • Offrire (to offer)
  • Seguire (to follow)
