Como saber se tem ou não crase? - Brasil Escola

Introduction

This tutorial provides a clear guide on how to determine when to use the crase in Portuguese. Understanding crase is essential for proper grammar in writing and speaking. The following steps will help you easily identify whether a crase is needed.

Step 1: Understand What Crase Is

• Crase is the fusion of two vowels, specifically the preposition "a" and the article "a" or "as."
• It is represented by a grave accent (à).
• Use crase before feminine nouns.

Step 2: Identify Situations for Crase Usage

• Crase is used in the following cases:
  • Before feminine nouns:
    • Example: "Vou à escola." (I’m going to the school.)
  • Before locutions that require a preposition and an article:
    • Example: "Aos cinco anos." (At five years old.)
  • Before proper names of places that are feminine:
    • Example: "Fui à Bahia." (I went to Bahia.)

Step 3: Apply the Substitution Test

• Replace the feminine noun with a masculine noun. If you can replace it with "ao," then crase is required.
  • Example:
    • Feminine: "Vou à escola." (I’m going to the school.)
    • Masculine: "Vou ao cinema." (I’m going to the cinema.)
  • Since "a" (to) + "a" (the) forms "à", crase is used.

Step 4: Recognize Common Exceptions

• Do not use crase in these situations:
  • Before masculine nouns:
    • Example: "Vou a pé." (I’m going on foot.)
  • Before singular nouns that are abstract (like "felicidade" or "saudade").
  • Before verbs:
    • Example: "Começar a trabalhar." (Start to work.)

Step 5: Familiarize Yourself with Expressions

• Some expressions always require crase:
  • "À medida que" (As)
  • "Àquela altura" (At that point)
• Memorizing these expressions can help avoid confusion.

Step 6: Practice Regularly

• Use exercises and quizzes available in grammar books or online resources to test your understanding.
• Review and correct your writing to identify any mistakes related to crase usage.

Conclusion

Understanding when to use crase can significantly improve your Portuguese writing and speaking skills. Remember to apply the substitution test, be aware of common exceptions, and practice regularly. For further learning, refer to additional resources or grammar guides to solidify your understanding.
