How to say “I study every day” in Portuguese basics

Introduction

Learn how to say and use the simple sentence I study every day in Brazilian Portuguese. This lesson teaches grammar, pronunciation, vocabulary, everyday examples, and common mistakes for complete beginners. By the end you will be able to form similar daily routine sentences and understand variations in conversation and writing.

Basic translation and the main phrase

The most natural translation for I study every day in Brazilian Portuguese is Eu estudo todos os dias. This is the clear, neutral way to state a daily habit using the present tense.

Breakdown of the phrase:

Eu — I (subject pronoun)

estudo — I study (first person singular of estudar)

todos os dias — every day / all the days

Why this structure works

In Portuguese, present tense often expresses habitual actions, unlike English where present simple is explicitly habitual. The verb estudar follows regular -ar conjugation patterns. The phrase todos os dias is a common time expression meaning every day and typically appears after the verb.

Conjugation basics for estudar

To make similar sentences you need the present tense conjugation of estudar. Here are the most important forms for beginners.

Eu estudo — I study

Tu estudas — You study (informal, rarely used in Brazil)

Você estuda — You study (formal or common spoken you)

Ele/ela estuda — He/she studies

Nós estudamos — We study

Vocês estudam — You all study

Eles/elas estudam — They study

Notes on pronouns and usage

In Brazilian Portuguese, subject pronouns are often optional because the verb ending indicates the subject. You can say Estudo todos os dias without Eu, and it will still mean I study every day. However, beginners may include Eu to be explicit.

Pronunciation tips

Pronounce Eu estudo todos os dias slowly at first:

Eu — sounds like ey-oo but quickly blended: eu

estudo — es-TOO-do (stress on the second syllable)

todos — TOH-dus

os — oosh or us depending on speed; in this phrase it is usually reduced to us: os

dias — DEE-ahs (the i is like English ee)

Putting it together: ey-oo es-TOO-do TOH-dus us DEE-ahs

Alternative expressions and synonyms

There are other natural ways to express the same idea:

Eu estudo diariamente — I study daily (more formal)

Estudo dia sim, dia não — I study every other day (literally day yes, day no)

Eu estudo todo dia — I study every day (colloquial; without os)

All of these are acceptable, but Eu estudo todos os dias is the safest choice for learners.

When to use each variant

Use todo dia in casual spoken Brazilian Portuguese. Use todos os dias in neutral speech and writing. Use diariamente when you want a more formal tone, for example in a short academic bio.

Common mistakes beginners make

Here are frequent errors and how to fix them.

Omitting subject-verb agreement: saying Eu estudar todos os dias — wrong. Correct: Eu estudo todos os dias.

Using present progressive incorrectly: saying Eu estou estudando todos os dias to mean habitual action — grammatically acceptable but often implies you are studying continuously right now. Prefer Eu estudo todos os dias for habits.

Forgetting the article os: saying Eu estudo todos dias — commonly heard and accepted informally, but the standard form is todos os dias.

Using tu forms in Brazil: Many learners use tu estudas because it exists in grammar books, but in most of Brazil you will hear você estuda or simply estuda in informal speech.
