Pronunciation

Pronunciation is not listed on this page: the verified tables do not include IPA for mudar, 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 mudar in every tense, you can recognise it in speech even before you can pronounce every form perfectly.

Three things to remember about mudar

  1. It is regular: every form follows the ordinary -ar pattern, so once you know the stem you can build the whole table. The only work is learning the endings, not memorising exceptions.
  2. The perfect tenses use ter: the pretérito perfeito composto is formed with ter in the present plus the past participle mudado. 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 gerund is mudando and the past participle is mudado: keep both in mind as you read the tables, because the gerund appears in progressive constructions and the past participle appears in every perfect tense. There is no present participle form listed for this verb in the verified tables. 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: “Eu mudar de ideias.”

✓ Right: “Eu mudo de ideias todos os dias.”

The infinitive mudar never takes a subject. After eu you need the conjugated present form mudo.

2. Using the wrong person’s form

✗ Wrong: “Eu mudas de ideias.”

✓ Right: “Eu mudo de ideias todos os dias.”

mudas is the tu form, not the eu form. Match the verb to the subject every time: eu goes with mudo.

3. Using the present for a finished past action

✗ Wrong: “Eu mudo de ideias ontem.”

✓ Right: “Eu mudei de ideias ontem.”

Ontem points to the past, so the present is wrong here. Use the pretérito perfeito mudei for a finished action yesterday.

4. Using the wrong auxiliary in the pretérito perfeito composto

✗ Wrong: “Eu sou mudado de ideias.”

✓ Right: “Eu tenho mudado de ideias esta semana.”

The pretérito perfeito composto of mudar is formed with ter plus the past participle mudado: the eu form is tenho mudado. Check the auxiliary in the table above before you build a perfect tense.

5. Using the indicative after a subjunctive trigger

✗ Wrong: “É importante que eu mudo de ideias.”

✓ Right: “É importante que eu mude de ideias.”

After é importante que Portuguese needs the subjunctive, so use mude here, not the indicative mudo.

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

✗ Wrong: “Eu tenho mudando de ideias.”

✓ Right: “Eu tenho mudado de ideias esta semana.”

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