Introduction

Conhecer means “to know”, and this page covers exactly one thing: conhecer 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 conhecer, 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 conhecer in the present. It means to know a person or a place, and to be acquainted with something, and it is different from saber, which means to know a fact. It is completely regular apart from its spelling: the stem-final c becomes ç before a and o, so the eu form is conheço and the subjunctive is conheça. For example: “Ele conhece a Maria todos os dias.” — “He knows Maria.” Everything on this page uses the forms of conhecer exactly as they are conjugated in the present, so you can trust every form you see here.

Conhecer in the Present — full table

Person Form
eu conheço
tu conheces
ele/ela conhece
nós conhecemos
vós conheceis
eles/elas conhecem
Gerund: conhecendo · Past participle: conhecido
The gerund is conhecendo, which you use with estar to say what is happening at the same time as the main action: “Conhecendo a Maria, aprendo muito.” — “While knowing Maria, I learn a lot.” The past participle is conhecido, which you use with ter in the perfect tenses: tenho conhecido 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 conhecer is used.
Pronunciation is not listed on this page: the verified tables do not include IPA for conhecer, so no pronunciation is given rather than an invented one.

How the present of conhecer is formed

The present tense of conhecer has six forms: eu conheço, tu conheces, ele conhece, nós conhecemos, vós conheceis, eles conhecem. Say them in order — eu, tu, ele, nós, vós, eles — and notice which forms share a stem and which do not. conhecer is regular: every form follows the standard -er 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. Because the stem-final c becomes ç before a and o, the eu form is conheço and the subjunctive eu form is conheça.

Two things about the present of conhecer 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 conhecemos and conheceis pays off in three tenses at once. Second, the present is the tense Portuguese uses where English would often use the continuous form, so conheço can mean both “I know” and “I am knowing” — context tells the listener which one you mean.

Because conhecer is regular in the present, the six forms follow the standard -er endings exactly. Once you know the pattern for one regular -er 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 conhecer

The present is not a single-purpose tense. Below are the five situations where you will use conhecer 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 conhecer is no exception. Use time expressions such as todos os dias, sempre or todas as semanas to make the routine explicit. Example: “Eu conheço a Maria todos os dias.” — “I know Maria.”

2. General truths

Use the present for things that are true in general, not just today. A fact about conhecer does not need a time expression, because it is true whenever you say it. Example: “Ele conhece a Maria todos os dias.” — “He knows Maria.”

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 conhecer 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 conhecemos a Maria todos os dias.” — “We know Maria.”

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 conheces a Maria todos os dias.” — “You know Maria.”

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 conhecer in the present is the tense that carries it. Example: “Eles conhecem a Maria todos os dias.” — “They know Maria.”

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 conhece a Maria todos os dias.” — “He knows Maria”
  • Pretérito Perfeito: “Ele conheceu a Maria ontem.” — “He knew Maria”
  • 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 conheço a Maria todos os dias.” — “I know Maria”
  • Pretérito Perfeito: “Eu conheci a Maria ontem.” — “I knew Maria”
  • 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 conheces a Maria todos os dias.” — “You know Maria”
  • Pretérito Perfeito: “Tu conheceste a Maria ontem.” — “You knew Maria”
  • 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 conheces a Maria.” Right: “Eu conheço a Maria todos os dias.” Why: The eu form is conheço, not conheces. conheces is the tu form. Mixing the two persons is the most common error with this verb.
  • Wrong: “Nós conheço a Maria.” Right: “Nós conhecemos a Maria todos os dias.” Why: Nós needs the nós form conhecemos. conheço belongs with eu only. Learn the six forms as two groups — singular and plural — and the pattern becomes automatic.
  • Wrong: “Eu conheço a Maria todos os dias ontem.” Right: “Eu conheci a Maria ontem.” Why: Ontem points to the past, so the present is wrong here. Use the pretérito perfeito conheci for a finished action yesterday.
  • Wrong: “Eu conhecer a Maria.” Right: “Eu conheço a Maria todos os dias.” Why: The infinitive conhecer never takes a subject. After eu you need the conjugated form conheço.
