Introduction
Mudar means “to change”, and this page covers exactly one thing: mudar in the present tense. The present is the tense Portuguese speakers reach for when they talk about what happens regularly, what is true in general, and what is happening right now. On this page you will find the full present table for mudar, how the tense is formed for this verb, the situations where it is used, how it differs from the pretérito perfeito, worked examples, the mistakes learners make most often, an eight-question quiz with explained answers, and answers to the questions students ask about mudar in the present. It means to change, and it is completely regular: mudo, mudas, muda, mudamos, mudais, mudam. Its pretérito perfeito is mudei, mudaste, mudou, and its participle is mudado. It also means to move house. The phrase mudo de ideias means I change my mind. For example: “Ele muda de ideias todos os dias.” — “He changes my mind.” Everything on this page uses the forms of mudar exactly as they are conjugated in the present, so you can trust every form you see here.
Mudar in the Present — full table
| Person | Form |
|---|---|
| eu | mudo |
| tu | mudas |
| ele/ela | muda |
| nós | mudamos |
| vós | mudais |
| eles/elas | mudam |
| Gerund: mudando · Past participle: mudado | |
| The gerund is mudando, which you use with estar to say what is happening at the same time as the main action: “Mudando de ideias, aprendo muito.” — “While changing my mind, I learn a lot.” The past participle is mudado, which you use with ter in the perfect tenses: tenho mudado is the pretérito perfeito composto, used for a completed action. Keep both forms in mind as you read the examples below, because the present is only one part of how mudar is used. | |

How the present of mudar is formed
The present tense of mudar has six forms: eu mudo, tu mudas, ele muda, nós mudamos, vós mudais, eles mudam. Say them in order — eu, tu, ele, nós, vós, eles — and notice which forms share a stem and which do not. mudar is regular: every form follows the standard -ar endings — -o, -as, -a, -amos, -ais, -am for -ar verbs; -o, -es, -e, -emos, -eis, -em for -er verbs; and -o, -es, -e, -imos, -is, -em for -ir verbs — so once you know the pattern you can build every tense from the stem. There are no surprises in any tense — the tables below are exactly what the endings predict. The present is the tense you will use most, so learn these six forms before you learn any other tense of this verb.
Two things about the present of mudar are worth noticing. First, the nós and vós forms are the anchor of the verb: the imperfect is built from the same stem, and the present subjunctive takes its nós and vós forms from the same stem, so learning mudamos and mudais pays off in three tenses at once. Second, the present is the tense Portuguese uses where English would often use the continuous form, so mudo can mean both “I change” and “I am changing” — context tells the listener which one you mean.
Because mudar is regular in the present, the six forms follow the standard -ar endings exactly. Once you know the pattern for one regular -ar verb, you know it for all of them — only the stem changes. That is why the present of a regular verb is the cheapest tense to learn in the whole language.
When to use the present of mudar
The present is not a single-purpose tense. Below are the five situations where you will use mudar in the present most often. Each one comes with a real example, so read the rule, then say the example out loud.
1. Habits and routines
The present tense is the tense of routine. When something happens every day, every week or every morning, the present is the natural choice, and mudar is no exception. Use time expressions such as todos os dias, sempre or todas as semanas to make the routine explicit. Example: “Eu mudo de ideias todos os dias.” — “I change my mind.”
2. General truths
Use the present for things that are true in general, not just today. A fact about mudar does not need a time expression, because it is true whenever you say it. Example: “Ele muda de ideias todos os dias.” — “He changes my mind.”
3. What is happening right now
The present also describes an action in progress at this very moment. Portuguese often prefers the simple present where English would use the continuous form, so a sentence with mudar in the present can mean both “I do this” and “I am doing this now”. Context tells the listener which one you mean. Example: “Nós mudamos de ideias todos os dias.” — “We change my mind.”
4. Scheduled future events
Portuguese uses the present for something already fixed in the near future, especially with a time expression. It sounds more certain than the future tense, because the plan is already made. Example: “Tu mudas de ideias todos os dias.” — “You change my mind.”
5. Narration and commentary
In stories, instructions and live commentary, the present brings the action into the room. A recipe, a game or a story told in the present feels immediate, and mudar in the present is the tense that carries it. Example: “Eles mudam de ideias todos os dias.” — “They change my mind.”
Present Tense vs Pretérito Perfeito: how to choose
The closest tense to the present is the pretérito perfeito, and learners mix them up constantly. The rule is simple: the present describes habits, general truths and what is happening now, while the pretérito perfeito describes one finished action in the past. The three pairs below use the same verb, so the only thing that changes is the time frame — and with it, the tense. Notice how the present sentences use words such as todos os dias or sempre, while the pretérito perfeito sentences use ontem or na semana passada. Those time words are your best clue when you are choosing a tense.
- Present Tense: “Ele muda de ideias todos os dias.” — “He changes my mind”
- Pretérito Perfeito: “Ele mudou de ideias ontem.” — “He changed my mind”
- The present sentence is a routine or a general truth; the pretérito perfeito sentence is one finished event. Todos os dias points to the present, ontem points to the pretérito perfeito.
- Present Tense: “Eu mudo de ideias todos os dias.” — “I change my mind”
- Pretérito Perfeito: “Eu mudei de ideias ontem.” — “I changed my mind”
- The present sentence is a routine or a general truth; the pretérito perfeito sentence is one finished event. Todos os dias points to the present, ontem points to the pretérito perfeito.
- Present Tense: “Tu mudas de ideias todos os dias.” — “You change my mind”
- Pretérito Perfeito: “Tu mudaste de ideias ontem.” — “You changed my mind”
- The present sentence is a routine or a general truth; the pretérito perfeito sentence is one finished event. Todos os dias points to the present, ontem points to the pretérito perfeito.

Common mistakes
These are the errors learners actually make with this verb in this tense. Each one shows the wrong version, the right version, and why the correction matters.
- Wrong: “Eu mudas de ideias.” Right: “Eu mudo de ideias todos os dias.” Why: The eu form is mudo, not mudas. mudas is the tu form. Mixing the two persons is the most common error with this verb.
- Wrong: “Nós mudo de ideias.” Right: “Nós mudamos de ideias todos os dias.” Why: Nós needs the nós form mudamos. mudo belongs with eu only. Learn the six forms as two groups — singular and plural — and the pattern becomes automatic.
- Wrong: “Eu mudo de ideias todos os dias ontem.” Right: “Eu mudei de ideias ontem.” Why: Ontem points to the past, so the present is wrong here. Use the pretérito perfeito mudei for a finished action yesterday.
- Wrong: “Eu mudar de ideias.” Right: “Eu mudo de ideias todos os dias.” Why: The infinitive mudar never takes a subject. After eu you need the conjugated form mudo.
