🟣 ACENTUAÇÃO: OXÍTONAS, PAROXÍTONAS e PROPAROXÍTONAS || Aula de Português

Summary

In this lesson, Professor Letícia Gois explains the rules of accentuation in Portuguese, focusing on the importance of understanding word stress (tonicity) and how to identify if a word is oxytone, paroxytone, or proparoxytone. She introduces key rules for each type, providing clear examples. The lesson covers accentuation of proparoxytone words (always accented), paroxytone words (with specific endings), oxytone words (accented when ending in certain vowels or consonants), and monosyllables. Additionally, Letícia discusses the use of accents in diphthongs, hiatus, and common exceptions, helping students master accentuation rules effectively.

Takeaways

• 😀 The lesson focuses on accentuation rules in Portuguese, specifically on how to identify and apply them.
• 😀 It is important to understand the tonic stress of words (whether a word is oxytone, paroxytone, or proparoxytone) to master accentuation rules.
• 😀 Words with stress on the antepenultimate syllable (proparoxytone) are always accentuated in Portuguese.
• 😀 Paroxytone words (with stress on the penultimate syllable) have specific rules based on their endings for when they are accented.
• 😀 Oxytone words (with stress on the last syllable) are accented only if they end in specific vowels or combinations like 'a', 'e', 'o', or 'em'.
• 😀 Monosyllabic words are accentuated if they are tonic (strong) and end in 'a', 'e', or 'o', regardless of whether they are followed by 's'.
• 😀 The rule for accentuating open diphthongs (such as 'ei', 'eu', and 'oi') only applies when they appear in oxytone or monosyllabic words.
• 😀 There has been a change in the accentuation of diphthongs in paroxytone words after the latest spelling reform.
• 😀 Iatonic words (with two vowels in separate syllables) with a tonic 'i' or 'u' must be accentuated, such as in words like 'baú' or 'país'.
• 😀 Exceptions to the iato rule include words with 'nh' following the tonic vowel, like 'rainha', and words with a diphthong preceding the tonic vowel, like 'feiúra'.

Q & A

What is the primary focus of this lesson on accentuation in Portuguese?

The lesson focuses on explaining the rules of accentuation in Portuguese, helping learners understand when and why words are accented, based on their syllabic structure.

What is the significance of understanding the tonic syllable of a word?

Understanding the tonic syllable is crucial for determining the stress pattern of the word (whether it's oxytone, paroxytone, or proparoxytone), which helps in applying accentuation rules.

What defines a proparoxytone word in Portuguese?

A proparoxytone word is defined as a word where the antepenultimate syllable is the strongest. These words are always accented in Portuguese.

Can you provide an example of a proparoxytone word?

Examples of proparoxytone words include 'pêssego', 'príncipe', and 'próximo'. All of these words are accented because their antepenultimate syllable is the strongest.

What are the rules for accentuating paroxytone words?

Paroxytone words are accented when they end in specific letters or combinations, such as R (e.g., 'açúcar'), I followed by S (e.g., 'táxi'), N (e.g., 'próton'), and other cases like 'l', 'u', or ditongos.

How do you differentiate between an oxytone and a paroxytone word?

An oxytone word has the last syllable as the strongest, while a paroxytone word has the penultimate syllable as the strongest.

What are some common rules for accentuating oxytone words?

Oxytone words are accentuated when they end in vowels like 'a', 'e', 'o', or in syllables that end with 's', such as 'paraná', 'café', or 'vovó'.

Why are certain monosyllabic words accented in Portuguese?

Monosyllabic words are accented when they are tonic (strong) and end in vowels like 'a', 'e', 'o', or when they are followed by 's' (e.g., 'você', 'nós').

What changed in accentuation rules regarding open diphthongs in the last orthographic reform?

The rule was updated so that open diphthongs (like 'ei', 'ou') are only accented when they appear in oxytone words or monosyllabic words. For example, 'herói' is accented, but 'heroico' is not.

What is an example of a word affected by the rule of iato (hiatus)?

An example is the word 'baú'. The 'u' forms a hiatus with the previous vowel, and as a result, the word is accented.
