Pronunciation

Pronunciation is not listed on this page: the verified tables do not include IPA for dimenticare, so no pronunciation is given rather than an invented one. Learn the spelling of the forms first, and listen to a native speaker for the sounds rather than trusting an invented transcription. The forms below are the ones that matter: once you can read dimenticare in every tense, you can recognise it in speech even before you can pronounce every form perfectly.

Three things to remember about dimenticare

  1. It is regular: every form follows the ordinary -are pattern, so once you know the stem you can build the whole table. The only work is learning the endings, not memorising exceptions. The -care stem keeps its hard c by inserting h before e and i, so the tu form is dimentichi and the future is dimenticherò.
  2. The perfect tenses use avere: the passato prossimo is formed with avere in the present plus the past participle dimenticato. The tables on this page give the participle in the masculine singular form, exactly as it appears in the verified dump; agreement with the subject is a separate step that depends on the sentence, not on the verb table.
  3. The participles are dimenticante and dimenticato: keep both in mind as you read the tables, because the present participle appears as an adjective and the past participle appears in every perfect tense. If you know those two forms and the present tense, you already know the skeleton of the whole conjugation.

Common mistakes

1. Using the infinitive instead of a conjugated form

✗ Wrong: “Io dimenticare le chiavi.”

✓ Right: “Io dimentico le chiavi ogni giorno.”

The infinitive dimenticare never takes a subject. After io you need the conjugated present form dimentico.

2. Using the wrong person’s form

✗ Wrong: “Io dimentichi le chiavi.”

✓ Right: “Io dimentico le chiavi ogni giorno.”

dimentichi is the tu form, not the io form. Match the verb to the subject every time: io goes with dimentico.

3. Using the present for a finished past action

✗ Wrong: “Io dimentico le chiavi ieri.”

✓ Right: “Io ho dimenticato le chiavi questa settimana.”

Yesterday points to the past, so the present is wrong here. Use the passato prossimo ho dimenticato for a finished action yesterday.

4. Using the wrong auxiliary in the passato prossimo

✗ Wrong: “Io sono dimenticato le chiavi.”

✓ Right: “Io ho dimenticato le chiavi questa settimana.”

The passato prossimo of dimenticare is formed with avere plus the past participle dimenticato: the io form is ho dimenticato. Check the auxiliary in the table above before you build a perfect tense.

5. Using the indicative after a subjunctive trigger

✗ Wrong: “È importante che io dimentico le chiavi.”

✓ Right: “È importante che io dimentichi le chiavi.”

After è importante che Italian needs the subjunctive, so use dimentichi here, not the indicative dimentico.

6. Using the gerund instead of the past participle in a perfect tense

✗ Wrong: “Io ho dimenticando le chiavi.”

✓ Right: “Io ho dimenticato le chiavi questa settimana.”

The perfect tenses need the past participle dimenticato, not the gerund dimenticando. The gerund belongs in progressive constructions, never after an auxiliary in a perfect tense.
