How to use “Cansado” and “Cansada” in Portuguese basics

Introduction

This article explains how to use the common Brazilian Portuguese adjectives Cansado and Cansada for complete beginners. You will learn meaning, gender agreement, short examples, common phrases, practical dialogs, and typical mistakes to avoid when speaking or reading everyday Brazilian Portuguese.

What do Cansado and Cansada mean?

Cansado and Cansada both mean tired in Brazilian Portuguese. The only difference is grammatical gender. Use Cansado with masculine nouns or male speakers, and Cansada with feminine nouns or female speakers.

Both words come from the verb cansar, which means to tire or to get tired. Context tells you whether someone is physically tired, mentally tired, or fed up.

Basic grammar: gender and agreement

Adjectives in Portuguese must agree in gender and number with the noun or subject they describe. For beginners, focus first on singular forms:

Masculine singular: Cansado

Feminine singular: Cansada

If you talk about more than one person, add -s: cansados (masculine plural) and cansadas (feminine plural). Example sentences below show these forms.

Examples with the verb ser and estar

Portuguese uses estar for temporary states and ser for more lasting conditions. For tiredness, use estar because being tired is usually temporary.

Eu estou Cansado. — I am tired. (said by a man)

Eu estou Cansada. — I am tired. (said by a woman)

Ele está cansado. — He is tired.

Ela está cansada. — She is tired.

Common mistakes beginners make

1. Wrong gender: Saying Estou cansada when a male speaker should say Estou Cansado. Always match adjective to the speaker or noun.

2. Using ser instead of estar: Saying Sou cansado to describe temporary tiredness. Use Estou cansado for most everyday tiredness.

3. Forgetting plural agreement: Saying Eles estão cansada instead of Eles estão cansados. For mixed groups, use masculine plural cansados.

4. Literal translation problems: In English you might say I am tired of this, and in Portuguese use Estou cansado disso or Estou cansada disso. Do not translate word-for-word other idioms that differ.

Tips to remember gender agreement quickly

1. When talking about yourself, choose the form that matches your gender: Eu estou Cansado (male), Eu estou Cansada (female).

2. For other people, listen for gender cues (ele, ela) or the noun: o aluno cansado, a aluna cansada.

3. Practice short fixed phrases so you do not need to build the sentence from scratch every time. For example, memorize Estou cansado(a) and Estou com sono.

Use tenho sono to say I am sleepy: Tenho sono, estou cansado. — I am sleepy, I am tired.

Listening and reading cues for beginners

When listening to conversations, watch for estar + adjective patterns: está cansado, estava cansada, estava exausto. These patterns signal states you can recognize quickly.
