How to Use “Cerca de” in Portuguese for Approximate Numbers

Introduction

Understanding how to express approximate numbers is essential for everyday conversation in Portuguese. This article explains how to use cerca de to talk about approximate quantities, ages, times, distances, prices, and more. Clear rules, native-like example sentences in Brazilian Portuguese, and useful usage notes will help English-speaking learners feel confident when estimating in Portuguese.

What does cerca de mean?

Cerca de is a common Portuguese expression used to indicate approximation. It is equivalent to English phrases like about, approximately, around, or roughly. Use cerca de when you want to give a number that is not exact but close enough for the context.

Basic structure

The typical structure is:

cerca de + number + noun (optional)

Examples:

cerca de 10 pessoas

cerca de 5 minutos

cerca de 20 reais

Grammar rules and word order

Here are the main grammar points to remember when using cerca de.

No agreement with gender or number

Cerca de does not change with gender or plural. The expression itself stays the same whether the noun is feminino or masculino, singular or plural. Only the following noun or number follows normal agreement rules.

Examples:

cerca de 1 hora

cerca de 3 horas

cerca de 1 quilo

cerca de 10 quilos

Use with numerals and quantities

You can use numerals, words for numbers, or approximate expressions after cerca de. It works with integers, decimals, percentages, and ranges.

Examples:

cerca de 50 pessoas

cerca de cinquenta pessoas

cerca de 2,5 litros

cerca de 10%

With units of time, distance, money, and age

Cerca de is very natural with units. Place the unit after the number as usual.

Examples:

cerca de 30 minutos

cerca de 100 metros

cerca de 200 reais

cerca de 40 anos

After verbs or at sentence start

You can use cerca de right after a verb or at the beginning of a sentence. Both options are grammatically correct; choose the word order that sounds most natural for emphasis.

Examples:

Chegamos cerca de 10 minutos atrasados.

Cerca de 10 minutos antes, ela ligou.

How precise is the approximation?

The implied margin of error depends on context and the magnitude of the number. For small numbers, cerca de might mean plus or minus one or two. For larger numbers, it could mean a wider range. Always consider the situation.

Small numbers

When you say cerca de with small counts, listeners expect a close approximation.

Examples:

Tem cerca de 3 pessoas na sala. (Probably 2–4 people)

Demora cerca de 5 minutos. (Maybe 4–6 minutes)

Large numbers

With large quantities, the acceptable range is wider. Cerca de 1.000 could mean a few hundred in either direction depending on context.

Examples:

O festival atrai cerca de 10.000 pessoas. (Could be 8.000–12.000)

Comprei cerca de 200 ações. (The exact margin depends on the situation)

Percentages and statistics

When used with percentages or statistics, cerca de signals approximation but can still be relatively precise depending on the speaker’s data.

Examples:

Cerca de 60% dos alunos passaram no exame. (Approximately 60 percent)

Pouco mais de metade, cerca de 55%. (About 55 percent)

Comparisons with similar expressions

Portuguese has other ways to express approximation. Understanding the nuance helps you pick the most natural option.

Approximately: mais ou menos

Mais ou menos is very colloquial and slightly more casual than cerca de. They are often interchangeable in spoken language.

Examples:

Tem mais ou menos 20 convidados. = Tem cerca de 20 convidados.

About/around: por volta de

Por volta de is similar in meaning and often used for times and dates. It can sound a bit more formal or neutral in certain contexts.

Examples:

Chegaremos por volta das 18h. = Chegaremos cerca das 18h.

Roughly: aproximadamente

Aproximadamente is more formal and often found in written contexts or data reporting. Use it for scientific, technical, or business language.

Examples:

O projeto custará aproximadamente 1 milhão de reais.

Practical examples and translations

Here are natural, context-rich sentences using cerca de, followed by literal English glosses and natural translations. These help you see how the phrase functions in conversation.

Vamos precisar de cerca de 3 sacos de cimento.
Literal: We will need about 3 bags of cement.
Natural: We will need around 3 bags of cement.

Ele mora a cerca de 15 minutos daqui.
Literal: He lives about 15 minutes from here.
Natural: He lives around 15 minutes away.

O ingresso custa cerca de 120 reais.
Literal: The ticket costs about 120 reais.
Natural: The ticket costs around 120 reais.

Literal: She is about 25 years old.
Natural: She is around 25 years old.

Cerca de metade da classe conseguiu a nota máxima.
Literal: About half of the class achieved the top grade.
Natural: Around half the class got top marks.

Negative forms and alternatives

When negating or giving a non-exact count in negative sentences, placement matters. You can also combine with verbs like faltar, sobrar, or restar.

Negative sentences

Place cerca de before the number even in negative constructions.

Examples:

Não tem cerca de 10 unidades disponíveis. (There are not about 10 units available)

Não temos cerca de 2 horas para terminar. (We do not have around 2 hours to finish)

Combining with faltar and sobrar

Use cerca de to estimate remaining quantities or time.

Examples:

Faltam cerca de 20 minutos para o filme acabar. (There are about 20 minutes left)
Sobram cerca de três peças na loja. (There are about three pieces left in the store)

Pronunciation and natural placement

Pronounce cerca de as a natural rhythm unit: cerca de. In connected speech Brazilians sometimes reduce the vowel sound of de, making it almost like d’ when spoken quickly, but in careful speech both words are clear.

Placement tip: Put cerca de close to the number for clarity. In sentences with many modifiers, keep the phrase near the noun it refers to so listeners know which quantity is approximate.

Cultural and usage notes

Brazilians use cerca de frequently in daily life: talking about arrival times, prices, quantities, and ages. It is polite and common because many situations do not require exactness. Using it correctly will make your speech sound natural and flexible.

In formal writing, especially in technical or legal contexts, you might prefer aproximadamente or give a specific range with between and and that in Portuguese is entre … e … for more precision.

Regional note: The expression is widely used across Brazil, with no strong regional restrictions. Some speakers prefer por volta de for times when talking about schedules or arrivals, but both are acceptable.

Common mistakes to avoid

1. Do not change cerca de to match gender or number. It is invariable.
2. Avoid putting the noun between cerca and de. The words must stay together: cerca de 10 pessoas, not cerca 10 de pessoas.
3. Be careful with placement: place cerca de next to the number it modifies to avoid ambiguity.

Quick reference summary

– Use cerca de to mean about, approximately, or around.
– Structure: cerca de + number + unit/noun.
– No agreement: cerca de never changes for gender or number.
– Works with time, distance, money, age, percentages, and counts.
– Alternatives: mais ou menos (colloquial), por volta de (for times/dates), aproximadamente (formal).

Conclusion

Cerca de is an essential, flexible expression for giving approximate numbers in Brazilian Portuguese. Use it with numerals, units, and nouns without changing its form, and keep it next to the number for clarity. Mastering cerca de will help you communicate naturally when exact numbers are unnecessary or unknown.
