Grammar Rule in 30 Seconds

Portuguese numbers 1 and 2 change gender to match the noun, while others remain neutral.

  • Number 1 (um/uma) must match the noun's gender: 'um carro' (masc), 'uma casa' (fem).
  • Number 2 (dois/duas) must match the noun's gender: 'dois homens' (masc), 'duas mulheres' (fem).
  • Numbers 3 through 100 do not change based on gender: 'três carros', 'três casas'.
Number (1 or 2) + Gender Agreement + Noun

Overview

Numbers are indispensable in Portuguese, forming the bedrock of daily communication, from simple counting to expressing complex quantities. Unlike English, Portuguese cardinal numbers introduce a critical grammatical concept: gender agreement. This applies specifically to the numbers um (one) and dois (two), and all hundreds from duzentos (two hundred) upwards.

Their form changes to match the grammatical gender of the noun they quantify.

Another fundamental characteristic is the use of the conjunction e (and) to connect numerical components. For instance, 25 is articulated as vinte e cinco (twenty and five). Mastering these foundational patterns ensures grammatical accuracy and clarity, establishing a crucial basis for developing advanced Portuguese proficiency.

While minor lexical and pronunciation differences exist between Brazilian Portuguese (BP) and European Portuguese (EP), the core numerical system and rules of agreement are largely consistent, facilitating broad comprehension.

This guide will equip you with a deep understanding of Portuguese numbers from A1, explaining not only what the rules are but why they function as they do, preparing you for real-world usage.

How This Grammar Works

Portuguese numbers operate as quantifiers, modifying nouns to specify how many. This function inherently links them to the concept of grammatical gender, a pervasive feature of the Portuguese language where all nouns are either masculine or feminine. When a number acts as a quantifier, it must sometimes align its gender with the noun it describes.
Most numbers in Portuguese are invariable, meaning their form remains constant regardless of the noun's gender or number. However, um and dois, alongside all hundreds from duzentos to novecentos, are variable, changing form to uma/duas or duzentas/novecentas respectively when modifying feminine nouns. This agreement is not arbitrary; it mirrors the adjective-noun agreement system in Portuguese.
Compound numbers are constructed using the conjunction e (and). This connector is crucial for linking units of tens and ones (e.g., trinta e sete – thirty-seven), hundreds and units/tens (e.g., cento e quatorze – one hundred fourteen), and even thousands with hundreds. The absence of e in specific contexts (like cem for exactly 100, or directly linking hundreds to thousands) is equally important to note.
Numbers can also function as labels or abstract concepts (e.g., o número um, a página dois), where they typically remain in their base (often masculine singular) form, as they are not directly quantifying a noun in these instances.

Formation Pattern

1
Forming Portuguese numbers involves a systematic build-up from basic units to complex combinations. Your mastery begins with memorizing the initial set and then applying clear rules for compounding them.

17
Example: You'd say um cachorro (one dog - masculine) but uma gata (one cat - feminine). Similarly, dois carros (two cars - masculine) but duas cadeiras (two chairs - feminine). Numbers like três are invariable, so it's always três livros (three books) and três mesas (three tables).
18
11-19: The Teens
19
These numbers are single words and do not use the e conjunction. They are invariable in gender, meaning their form does not change, regardless of the noun's gender.

29
Example: You say quinze dias (fifteen days - masculine) and quinze noites (fifteen nights - feminine). Notice how the number quinze itself does not change. Similarly, dezesseis alunos (sixteen students) or dezasseis alunas (sixteen female students).
30
20-99: Tens and Units
31
These numbers combine a tens unit with a single unit using the conjunction e. All the tens units (e.g., vinte, trinta) are invariable in gender.
32
| Number | Portuguese Term |

| 60 | sessenta |
39
| 70 | setenta |
40
| 80 | oitenta |
41
| 90 | noventa |
42
To form a compound number, state the tens unit, followed by e, then the single unit. Remember that um/uma and dois/duas will still agree in gender with the noun they ultimately refer to. For example, 21 is vinte e um (for masculine nouns) or vinte e uma (for feminine nouns).
43
Example: You would say vinte e três meninos (twenty-three boys) or vinte e três meninas (twenty-three girls) because três is invariable. However, for 31, it's trinta e um dias (thirty-one days) but trinta e uma semanas (thirty-one weeks).
44
100-999: Hundreds
45
The formation of hundreds introduces a crucial distinction. Cem is used only for the exact number 100. For any number from 101 to 199, you must use cento e followed by the remaining digits. From 200 upwards, the hundreds themselves agree in gender with the noun they modify.
46
| Number | Masculine | Feminine |
47
|:-------|:---------------|:---------------|
48
| 100 | cem | cem |
49
| 200 | duzentos | duzentas |
50
| 300 | trezentos | trezentas |
51
| 400 | quatrocentos | quatrocentas |
52
| 500 | quinhentos | quinhentas |
53
| 600 | seiscentos | seiscentas |
54
| 700 | setecentos | setecentas |
55
| 800 | oitocentos | oitocentas |
56
| 900 | novecentos | novecentas |
57
For compound numbers within the hundreds, connect the hundreds with e to the tens/units. For example, 123 is cento e vinte e três, and 250 is duzentos e cinquenta (for masculine nouns) or duzentas e cinquenta (for feminine nouns).
58
Example: You'd say cem páginas (one hundred pages). But for 105, it's cento e cinco páginas. For 200, duzentos livros (two hundred books) but duzentas canetas (two hundred pens). For 940, it's novecentos e quarenta alunos (nine hundred forty students) or novecentas e quarenta alunas (nine hundred forty female students).
59
1.000+: Thousands, Millions, and Beyond
60
mil (1,000): This number is invariable in gender and number. Always use mil directly; never um mil. It behaves like an adjective when quantifying. To express larger thousands, simply state the preceding number. For instance, 2,000 is dois mil, and 1,999 is mil novecentos e noventa e nove. The e connects thousands to hundreds, and tens to units.
61
Example: mil euros (one thousand euros), dois mil e vinte e seis (two thousand twenty-six).
62
milhão (1,000,000): This is a masculine noun that agrees in number (plural milhões). Crucially, milhão and milhões require the preposition de (of) when followed by the noun they quantify. This is a common point of confusion for learners.
63
Example: um milhão de dólares (one million dollars), dois milhões de habitantes (two million inhabitants).
64
bilhão (1,000,000,000 - BP) / mil milhão (EP) / bilião (EP for 10^12): This is a significant difference between Brazilian and European Portuguese. In BP, bilhão refers to one billion (10^9, short scale). In EP, mil milhão is used for 10^9, and bilião refers to one trillion (10^12, long scale). Like milhão, these are masculine nouns, agree in number, and require de before a quantified noun.
65
Example (BP): um bilhão de reais (one billion Brazilian reals).
66
Example (EP): mil milhões de euros (one billion euros), dois biliões de pessoas (two trillion people - if used for 10^12).

Gender & Agreement

The concept of gender agreement for numbers is a cornerstone of accurate Portuguese usage. It's not a random rule but a direct consequence of how certain numbers function as adjectives that modify nouns, taking on their gender.
  • The Big Three (and the Hundreds): Only um, dois, and the hundreds (duzentos through novecentos) exhibit gender agreement. All other cardinal numbers are invariable.
  • Um vs. Uma: When quantifying a singular noun, um is used for masculine nouns and uma for feminine nouns.
Example: um amigo (one friend, masculine), uma amiga (one friend, feminine).
  • Dois vs. Duas: Similarly, for plural nouns, dois is used for masculine plural nouns and duas for feminine plural nouns.
Example: dois gatos (two cats, masculine), duas gatas (two cats, feminine).
  • Duzentos through Novecentos: These hundreds agree in gender with the noun they modify, mirroring the dois/duas pattern.
Example: duzentos euros (two hundred euros, masculine), duzentas moedas (two hundred coins, feminine).
  • Invariable Numbers: The majority of Portuguese numbers (from três to dezenove, all tens vinte, trinta, etc., and mil) do not change their form. They are gender-neutral.
Example: três homens (three men), três mulheres (three women). quarenta livros (forty books), quarenta revistas (forty magazines).
  • Numbers as Nouns or Labels: When a number is not directly quantifying a noun but rather acting as a label or an abstract concept, it typically defaults to its masculine form. This happens when the number itself is the subject or object, or when referring to a general concept like a number in a sequence.
Example: O número um da lista (The number one on the list – um here is part of a nominal phrase, not quantifying).
Example: A página dois (Page two – dois functions as a label, not modifying página for gender).

When To Use It

Numbers are ubiquitous in daily Portuguese, serving various functions. Understanding their proper context is key to natural communication.
  • Quantifying Nouns: This is the most direct use, where numbers specify the quantity of an item. Remember to apply gender agreement where necessary.
Example: Eu tenho cinco canetas e dois lápis. (I have five pens and two pencils.)
Example: Precisamos de duas cadeiras novas. (We need two new chairs.)
  • Dates: Numbers are essential for expressing specific dates. The day of the month uses cardinal numbers, except for the first, which uses the ordinal primeiro/primeira.
Example: Hoje é vinte e cinco de março. (Today is March twenty-fifth.)
Example: A festa será em dez de abril. (The party will be on April tenth.)
  • Time: Telling time relies heavily on numbers. Horas (hours) is a feminine noun, so numbers quantifying hours will reflect this.
Example: São sete horas da manhã. (It's seven in the morning.)
Example: A reunião começa às duas da tarde. (The meeting starts at two in the afternoon – duas agrees with horas, which is implied).
  • Age: Expressing age consistently uses the verb ter (to have) followed by the number of anos (years, masculine plural).
Example: Ele tem vinte e um anos. (He is twenty-one years old.)
Example: Minha irmã tem dezenove anos. (My sister is nineteen years old.)
  • Prices and Currency: When stating prices, numbers precede the currency unit. Currency names like euro (masculine) or real (masculine, plural reais) will determine agreement for um/dois/hundreds.
Example: Custa trinta e cinco euros. (It costs thirty-five euros.)
Example: São cento e vinte reais. (It is one hundred twenty Brazilian reals.)
  • Measurements: Whether for distance, weight, or volume, numbers combine with measurement units.
Example: A casa fica a dois quilômetros daqui. (The house is two kilometers from here.)
Example: Eu quero cem gramas de queijo. (I want one hundred grams of cheese.)
  • Phone Numbers and Addresses: These are typically read digit by digit or in small groups, with the numbers generally treated as masculine and invariable in this context.
Example: Meu telefone é nove, oito, sete, seis, um, dois, três, quatro. (My phone is 98761234.)

Common Mistakes

Portuguese numbers present specific challenges for learners. Being aware of these common pitfalls will help you avoid them.
  • Forgetting Gender Agreement for um/dois/Hundreds: This is perhaps the most frequent error. Learners often use the masculine form universally. Remember that uma for feminine singular, duas for feminine plural, and duzentas/trezentas, etc., for feminine hundreds are non-negotiable.
Incorrect
✗ * duas livros (should be dois livros)
✗ * cem e vinte (should be cento e vinte when not exactly 100)
✗ * quinhentos casas (should be quinhentas casas)
  • Using um mil instead of mil: In Portuguese, mil (one thousand) stands alone. You do not precede it with um.
✗* Eu tenho um mil reais.
✓* Eu tenho mil reais. (I have one thousand reais.)
  • Omitting e in Compound Numbers: The conjunction e is vital for connecting tens and units, and hundreds to tens/units. Skipping it results in awkward or incorrect phrasing.
✗ * vinte cinco (should be vinte e cinco)
✗ * cento cinco (should be cento e cinco)
  • Confusing cem and cento e: Cem is exclusively for the exact quantity of 100. Any number between 101 and 199 begins with cento e.
✗* cem e dez (should be cento e dez)
✓* Cem pessoas vieram. (One hundred people came.)
✓ * Cento e uma pessoas vieram. (One hundred one people came.)
  • Forgetting de after milhão/bilhão: When milhão or bilhão quantifies a noun, the preposition de is mandatory, acting like 'of' in English 'a million of dollars'. This structure treats milhão as a noun in itself.
✗* dois milhões carros
✓* dois milhões de carros (two million cars)
  • BP vs. EP for bilhão/bilião: Be mindful of the significant difference in scale for bilhão (BP = 10^9) and bilião (EP = 10^12, with 10^9 being mil milhão). Using the wrong term can lead to huge misinterpretations of quantity.

Common Collocations

Numbers frequently appear with specific nouns and expressions. Learning these collocations helps you use numbers naturally and idiomatically.
  • Time (horas, minutos, segundos):
  • uma hora (one hour, fem. uma)
  • duas horas (two hours, fem. duas)
  • dez minutos (ten minutes)
  • trinta segundos (thirty seconds)
  • Money (reais, euros, dólares):
  • um real (one Brazilian real, masc. um)
  • uma nota de cem reais (a one hundred reais bill – cem is invariable)
  • quinze euros (fifteen euros)
  • Age (anos):
  • vinte anos (twenty years old)
  • trinta e dois anos (thirty-two years old – dois agrees with anos)
  • Counting Items (pessoas, coisas, livros, casas):
  • cinco pessoas (five people)
  • dez coisas (ten things)
  • vinte e um livros (twenty-one books – um agrees with livros)
  • cento e duas casas (one hundred two houses – duas agrees with casas)
  • Measurements (metros, quilos, litros):
  • um metro (one meter, masc. um)
  • dois quilos (two kilos, masc. dois)
  • três litros (three liters)
  • Ordinal vs. Cardinal (a brief note): While this chapter focuses on cardinal numbers, be aware that o número um (the number one) uses the cardinal form, but a primeira vez (the first time) uses an ordinal. Don't confuse the two, especially for 'one'.

FAQ (8)

Portuguese nouns have gender. 'Um' is the masculine form, and 'uma' is the feminine form.

Yes, the last digit must agree. 'Vinte e um' (masc) vs 'Vinte e uma' (fem).

100 is 'cem', which is invariant. But 200 is 'duzentos/duzentas', which inflects.

Yes, 'duas' is used for feminine nouns like 'duas mulheres'.

Use the same rules. 'Duas pessoas' (feminine).

Very few. The gender agreement rule is standard in both Brazil and Portugal.

Try to learn the noun with its article (o/a). If you're unsure, 'um' is a safer bet for masculine.

Yes, 'Tenho dois' (I have two).
