- 'Noventa' is the Portuguese word for ninety (90).
- It's a cardinal number used for counting and quantities.
- Commonly used for ages, prices, and durations.
- Essential for basic numerical understanding in Portuguese.
- Definition
- 'Noventa' is the Portuguese word for the number ninety. It represents the quantity that comes after eighty-nine and before ninety-one. It is a fundamental number used in counting, expressing quantities, ages, prices, dates, and many other everyday situations where numbers are involved. Understanding 'noventa' is crucial for basic numerical comprehension in Portuguese.
- Usage
- This number is used extensively in daily life. For example, when stating someone's age if they are ninety years old, discussing the price of an item that costs ninety units of currency, or referring to the ninetieth day of a month or year. It's part of the standard numerical sequence and is encountered frequently in spoken and written Portuguese.
Ten times nine equals noventa.
The train arrives at noventa minutes past the hour.
- Numerical Context
- 'Noventa' is part of the cardinal numbers in Portuguese, which are used for counting. It follows 'oitenta e nove' (eighty-nine) and precedes 'cem' (one hundred) when counting upwards. Its position in the numerical sequence is fixed, making it predictable and essential for arithmetic and quantitative expressions. When learning Portuguese numbers, mastering the sequence from twenty upwards, including 'noventa', is a key milestone.
- Basic Usage
- 'Noventa' is typically used as a determiner or a numeral adjective, indicating a quantity. It directly precedes the noun it quantifies or stands alone when the context is clear. For instance, 'tenho noventa livros' means 'I have ninety books'. Here, 'noventa' specifies the number of books. In sentences where the number is the subject or object, it can stand by itself: 'Noventa é um número par' (Ninety is an even number).
- Expressing Age
- When talking about age, 'noventa' is used to state that someone is ninety years old. The common structure is 'ter [number] anos'. So, 'Ele tem noventa anos' translates to 'He is ninety years old'. This is a very frequent application of the number.
- Prices and Quantities
- In commercial contexts, 'noventa' is used to express prices or quantities of items. For example, 'O preço é noventa reais' means 'The price is ninety reais'. If you are buying multiple items, you might say, 'Comprei noventa maçãs' ('I bought ninety apples').
- Time and Dates
- 'Noventa' can appear in time expressions, often related to minutes or durations. For instance, a meeting might last 'noventa minutos' (ninety minutes). While less common for specific dates (as months only go up to twelve and days up to thirty-one), it can be used in contexts like 'o noventa por cento' (ninety percent).
- In Mathematical Operations
- 'Noventa' is a standard number in mathematical calculations. You might hear or read sentences like 'Noventa dividido por dez é nove' ('Ninety divided by ten is nine'). It functions as any other cardinal number in arithmetic.
My grandmother will be noventa next year.
This book has almost noventa pages.
- Everyday Conversations
- You'll hear 'noventa' constantly in everyday Portuguese conversations. When people discuss their ages, especially older individuals, 'noventa' is a common number. For example, during a family gathering, someone might mention, 'O meu tio avô tem noventa anos' ('My great-uncle is ninety years old'). It's also used when talking about how many items someone has, like 'Comprei noventa quilos de batatas' ('I bought ninety kilos of potatoes') for a large event.
- Shopping and Commerce
- In shops, markets, and during any transaction, prices are frequently stated. If an item costs ninety euros, dollars, or any local currency, the vendor will say, 'São noventa euros' ('It's ninety euros'). Similarly, if you're buying something in bulk, like 'noventa metros de tecido' ('ninety meters of fabric'), you'll encounter the word.
- Public Announcements and Information
- Public transport announcements might mention durations involving 'noventa' minutes. For example, 'O autocarro vai demorar noventa minutos para chegar' ('The bus will take ninety minutes to arrive'). In news reports or statistical data, you might hear percentages like 'noventa por cento' ('ninety percent') of the population, or figures related to population size, distance, or measurements.
- Educational Settings
- In schools, teachers use numbers extensively. When teaching arithmetic, 'noventa' will be used in examples and exercises. Students learning Portuguese will encounter it in textbooks, on worksheets, and during lessons focused on numbers, measurements, and quantities.
- Media and Entertainment
- Radio, television, and movies frequently use numbers. A sports commentator might say a player scored 'noventa pontos' ('ninety points'). A documentary could discuss historical events from 'noventa anos atrás' ('ninety years ago'). Game shows often involve numbers in their challenges and prizes.
The flight duration is approximately noventa minutes.
We need to buy noventa chairs for the event.
- Confusing with Similar Numbers
- A common mistake for beginners is confusing 'noventa' (ninety) with similar-sounding numbers or numbers in the same range. For example, confusing it with 'oitenta' (eighty) or 'cem' (one hundred). Pronunciation is key here; practicing the distinct sounds of each number will help prevent errors. Ensure you can clearly differentiate the 'nov-' sound from 'oit-' or the '-enta' ending from other number endings.
- Incorrect Placement in Compound Numbers
- While 'noventa' itself is a single word for ninety, learners might struggle when constructing numbers in the nineties, like 'noventa e um' (ninety-one). The mistake could be omitting the 'e' (and) or misplacing the unit number. For instance, saying 'noventa um' instead of 'noventa e um'. Remember that numbers from twenty-one to ninety-nine (except for multiples of ten) generally use 'e' to connect the tens and units.
- Gender and Number Agreement (Not Applicable for 'Noventa')
- Unlike many Portuguese nouns and adjectives, cardinal numbers like 'noventa' do not change their form to agree in gender or number with the noun they modify. A common error might be to try to make 'noventa' plural or feminine, which is incorrect. For example, saying 'noventas' when referring to multiple groups of ninety is generally not standard usage for cardinal numbers. 'Noventa' remains 'noventa' regardless of the noun.
- Over-reliance on English Numbering
- Some learners might mentally translate from English, which can lead to errors in pronunciation or structure. For instance, thinking of 'ninety' and then trying to pronounce 'noventa' with an English accent. It's important to learn the Portuguese pronunciation rules and practice them specifically. Also, understanding that Portuguese number construction can differ from English is vital.
- Misunderstanding Context
- While 'noventa' is a straightforward number, context can sometimes be tricky. For instance, confusing its use as a cardinal number (counting) with ordinal numbers (position). While 'noventa' itself is cardinal, in a sentence like 'o capítulo noventa' (chapter ninety), it functions as a number, but in other contexts, ordinal numbers would be used for sequence. Ensure you understand if the context requires a cardinal or ordinal number.
Incorrect: 'Tenho noventas euros.'
Correct: 'Tenho noventa euros.'
Incorrect: 'São oitenta e dez pessoas.'
Correct: 'São noventa pessoas.'
- 'Oitenta' (Eighty)
- 'Oitenta' is the number that immediately precedes 'noventa' in the counting sequence. It represents the quantity of eighty. While both are cardinal numbers in the higher range, they are distinct values. For example, 'Tenho oitenta livros' (I have eighty books) versus 'Tenho noventa livros' (I have ninety books).
- 'Cem' (One Hundred)
- 'Cem' is the number that follows 'noventa e nove' (ninety-nine). It signifies the quantity of one hundred. 'Noventa' is the penultimate number before reaching the round figure of one hundred. For instance, 'O projeto custou noventa mil euros' (The project cost ninety thousand euros) is different from 'O projeto custou cem mil euros' (The project cost one hundred thousand euros).
- 'Noventa e um', 'Noventa e dois', etc. (Ninety-one, Ninety-two, etc.)
- These are specific numbers within the nineties range. 'Noventa' is the base number for this decade. 'Noventa e um' means ninety-one, 'noventa e dois' means ninety-two, and so on, up to 'noventa e nove' (ninety-nine). They are direct extensions of 'noventa'. For example, 'Ele comprou noventa e cinco bilhetes' (He bought ninety-five tickets) is a more specific quantity than just 'noventa'.
- 'Meia dúzia' (Half a dozen) / 'Dúzia' (Dozen)
- These are smaller, specific quantities. A dozen is twelve, and half a dozen is six. While 'noventa' refers to a much larger quantity, these terms are sometimes used colloquially for smaller amounts. They represent different scales of numbers. You wouldn't use 'noventa' to describe buying a dozen eggs.
- 'Por cento' (Percent)
- 'Noventa' can be used in conjunction with 'por cento' to form 'noventa por cento' (ninety percent). While 'noventa' is a standalone number, 'noventa por cento' represents a fraction of a whole. For example, 'Noventa por cento dos alunos passaram no exame' (Ninety percent of the students passed the exam) is a statement about proportion, not just a quantity of ninety individuals.
Comparison: 'Tenho oitenta carros.' vs. 'Tenho noventa carros.' (Eighty cars vs. Ninety cars)
Comparison: 'O valor é noventa reais.' vs. 'O valor é cem reais.' (The price is ninety reais vs. The price is one hundred reais)
How Formal Is It?
豆知識
The structure of numbers in Portuguese, like in many Romance languages, often reflects their Latin origins. The 'ginta' suffix for tens (e.g., 'viginta' for twenty, 'triginta' for thirty, 'nonaginta' for ninety) is a clear indicator of this lineage. This pattern helps linguists trace the evolution of numerals across different languages.
発音ガイド
- Pronouncing the 'v' as a 'b'.
- Incorrect stress placement, e.g., stressing the first syllable.
- Pronouncing the final 'a' too strongly, instead of a reduced vowel sound.
- Confusing the vowel sound in 'ven' with other sounds.
- Adding an extra syllable or misplacing the 'n'.
難易度
At A1/A2 levels, 'noventa' is easily recognizable in written text when used in simple numerical contexts like prices or quantities. Its meaning is straightforward and directly corresponds to the number 90.
Writing 'noventa' correctly is straightforward for beginners once they learn the spelling. The main challenge might be its placement in compound numbers or ensuring correct spelling.
Pronunciation can be slightly challenging due to stress and vowel reduction. Distinguishing it from similar numbers like 'oitenta' requires practice. However, it's a common word, so exposure helps.
Recognizing 'noventa' in spoken Portuguese requires familiarity with its pronunciation and stress. It can sometimes be confused with similar numbers if spoken quickly or unclearly.

Neutral間違えやすい
Both are cardinal numbers in the higher range (80s and 90s) and can sound similar if not pronounced carefully.
'Oitenta' means eighty (80), while 'noventa' means ninety (90). They represent different numerical values and have distinct pronunciations, particularly at the beginning of the word ('oit-' vs. 'nov-').
Eu tenho <mark class='bg-emerald-200 dark:bg-emerald-800 px-0.5 rounded'>oitenta</mark> livros. (I have eighty books.) vs. Eu tenho <mark class='bg-emerald-200 dark:bg-emerald-800 px-0.5 rounded'>noventa</mark> livros. (I have ninety books.)
Both are large, round numbers that often appear in similar contexts (e.g., prices, quantities).
'Cem' means one hundred (100), whereas 'noventa' means ninety (90). 'Cem' represents a greater quantity. The spelling and pronunciation are also distinct ('cem' vs. 'noventa').
O concerto teve <mark class='bg-emerald-200 dark:bg-emerald-800 px-0.5 rounded'>cem</mark> mil espectadores. (The concert had one hundred thousand spectators.) vs. O concerto teve <mark class='bg-emerald-200 dark:bg-emerald-800 px-0.5 rounded'>noventa</mark> mil espectadores. (The concert had ninety thousand spectators.)
Both words start with 'nov-' and share the root related to the digit nine.
'Nove' is the number nine (9). 'Noventa' is ninety (90), which is ten times nine. 'Nove' is a single digit, while 'noventa' is a tens number.
Tenho <mark class='bg-emerald-200 dark:bg-emerald-800 px-0.5 rounded'>nove</mark> anos. (I am nine years old.) vs. Tenho <mark class='bg-emerald-200 dark:bg-emerald-800 px-0.5 rounded'>noventa</mark> anos. (I am ninety years old.)
These are consecutive numbers, and learners might mistakenly use 'noventa' when they mean 'noventa e um', or vice-versa.
'Noventa' is exactly ninety (90). 'Noventa e um' is ninety-one (91). The difference is one unit, but they are distinct numbers.
Comprei <mark class='bg-emerald-200 dark:bg-emerald-800 px-0.5 rounded'>noventa</mark> quilos. (I bought ninety kilos.) vs. Comprei <mark class='bg-emerald-200 dark:bg-emerald-800 px-0.5 rounded'>noventa</mark> e um quilos. (I bought ninety-one kilos.)
This word shares the same root and sounds similar to 'noventa'.
'Noventa' is the number ninety. 'Noventena' is a noun referring to a period of ninety days. They are related but have different grammatical functions and meanings.
A cerimónia durou <mark class='bg-emerald-200 dark:bg-emerald-800 px-0.5 rounded'>noventa</mark> minutos. (The ceremony lasted ninety minutes.) vs. A <mark class='bg-emerald-200 dark:bg-emerald-800 px-0.5 rounded'>noventena</mark> de espera foi longa. (The ninety-day wait was long.)
