Numeral - Artigo [Prof Noslen]

Summary

This video lesson delves into the classification and usage of numerals in the Portuguese language. It covers the four main types of numerals: cardinal, ordinal, multiplicative, and fractional, explaining their definitions and providing examples. Key rules for using these numerals in different contexts, such as in legal articles and before nouns, are also discussed. The lesson emphasizes the difference between the indefinite article 'um' and the numeral 'um'. Practical examples help illustrate when and how to use each type of numeral in a grammatically correct manner.

Takeaways

• 😀 Numerals in Portuguese can be classified into four categories: cardinal, ordinal, multiplicative, and fractional.
• 😀 Cardinal numerals refer to quantity (e.g., one, two, three, etc.).
• 😀 Ordinal numerals indicate order (e.g., first, second, third, etc.).
• 😀 Multiplicative numerals express multiplication (e.g., double, triple, quadruple).
• 😀 Fractional numerals represent fractions (e.g., half, one-third).
• 😀 When numerals are used with nouns, ordinals are typically used for numbers from 1 to 10, but cardinal numerals are used for numbers greater than 10.
• 😀 In legal contexts, ordinals are used only for numbers 1 through 9 (e.g., Article 9), and cardinal numerals are used above 10 (e.g., Article 10).
• 😀 If a numeral is placed before a noun, it is considered ordinal (e.g., 22nd marathon).
• 😀 When a numeral is placed after a noun, it is treated as a cardinal number (e.g., marathon 22).
• 😀 The numeral 'um' (one) can be both a numeral and an article depending on its usage in context (e.g., 'um peixe' vs. 'fui à uma pescaria').
• 😀 The difference between the indefinite article 'um' and the numeral 'um' is based on whether the noun is general or specific.

Q & A

What are the four types of numerals discussed in the lesson?

The four types of numerals discussed are cardinal, ordinal, multiplicative, and fractional.

What does the cardinal numeral refer to?

The cardinal numeral refers to quantity, such as one, two, three, ten, seventy, or one hundred.

What is the main function of the ordinal numeral?

The ordinal numeral indicates the order or position of something, such as first, second, third, or twenty-first.

What is a multiplicative numeral?

A multiplicative numeral refers to multiples, such as double, triple, quadruple, quintuple, and septuple.

What does a fractional numeral represent?

A fractional numeral represents parts or divisions, such as half, a third, or one-fourth.

How are ordinal numerals used when they follow a noun?

When ordinal numerals follow a noun, they are typically used for numbers 1 to 10. For example, 'Pope John Paul I', 'Pope John Paul II', 'Pope John Paul IX'.

How does the use of ordinal numerals change for numbers above 10?

For numbers above 10, the numeral becomes cardinal. For example, 'Pope John Paul 12' instead of 'Pope John Paul XII'.

How are ordinal numerals used in legal contexts such as articles and laws?

In legal contexts, ordinal numerals are used for numbers 1 to 9. For example, 'Article 9', 'Law 9'. For numbers above 9, cardinal numerals are used, such as 'Article 10' or 'Law 10'.

What happens when a Roman numeral is placed before a noun?

When a Roman numeral is placed before a noun, it always takes the form of an ordinal numeral. For example, '22nd marathon' when the Roman numeral 'XXII' is placed before 'marathon'.

How can you distinguish between the numeral 'one' as an article and as a number?

The numeral 'one' is used as an article when it generalizes a noun, as in 'a fish was caught'. It is used as a number when it specifies a quantity, as in 'I caught one fish'.
