Takeaways

• 😀 Crase is the combination of the preposition 'a' and the article 'a' or demonstrative pronouns like 'aquela', 'aquele', and 'aquilo'.
• 😀 Crase is marked by the grave accent (à), not to be confused with the acute accent (á).
• 😀 Crase is required before feminine words, such as 'à praia' (to the beach) and 'à festa' (to the party).
• 😀 To check if crase is necessary, substitute the feminine word with a masculine one. If the sentence still makes sense with 'ao' or 'aos', crase is used.
• 😀 Crase is used to indicate the number of hours, e.g., 'às 4 horas' (at 4 o'clock), but not when prepositions like 'para', 'desde', or 'entre' are involved.
• 😀 Certain adverbial, prepositional, and conjunctive expressions require crase, such as 'à noite' (at night) and 'às pressas' (in a hurry).
• 😀 Crase is **not** used in expressions like 'a pé' (on foot), 'a cavalo' (on horseback), or 'a prazo' (on credit) because the nouns are masculine.
• 😀 Avoid crase when words are repeated, such as in 'passo a passo' (step by step) or 'dia a dia' (day by day).
• 😀 Crase never occurs before verbs. For example, 'comecei a estudar' (I started to study) has no crase because 'estudar' is a verb.
• 😀 In sentences with proper nouns like 'Machado de Assis', no crase is used, as proper names do not take an article.
• 😀 To test your understanding, always check for contractions (a + a = à) in contexts involving feminine words or phrases.

Q & A

What is crase in Portuguese grammar?

Crase is the use of the accent grave (`à`), which occurs when the preposition 'a' merges with the article 'a' or with a feminine demonstrative pronoun (like 'aquela').

When is crase applied before feminine words?

Crase is used before feminine nouns or adjectives when there is a contraction of the preposition 'a' with the article 'a' or a feminine demonstrative pronoun.

How can you check if crase is needed before a word?

To check if crase is needed, substitute the feminine word with a masculine one. If the resulting sentence has 'ao' (the contraction of 'a' and 'o'), then crase is used.

What is an example of crase being used correctly?

An example is 'Meus amigos foram à praia', where crase is used because 'praia' is a feminine noun.

What are the rules for using crase with time indications?

Crase is used before time expressions, such as 'às 4 horas' or 'às 19 horas', when referring to a specific time. However, if prepositions like 'para', 'desde', or 'após' precede the time expression, crase is not used.

What is a common mistake regarding the abbreviation of hours?

A common mistake is writing 'h' as uppercase. The correct abbreviation for hours is 'h' in lowercase.

No, crase does not occur before verbs. For example, 'comecei a estudar' does not have crase because 'estudar' is a verb.

Why does crase not apply in the phrase 'escrevia a Machado de Assis'?

Crase does not apply because the verb 'escrevia' is followed by a proper noun (Machado de Assis), which does not require a preposition. Therefore, no contraction occurs.
