At the A1 level, learners are expected to recognize and use basic cardinal numbers from 1 to 100. 'Dezasseis' is a core vocabulary word for this level. Students should be able to use it to state their age (e.g., 'Tenho dezasseis anos'), count objects (e.g., 'dezasseis laranjas'), and understand basic time references in a 24-hour format. The focus is on correct spelling (remembering the 'a' and the 'ss') and basic pronunciation. A1 learners should also be able to identify the number in simple listening tasks, such as hearing a price at a shop or a platform number at a train station. The primary goal is functional use in everyday transactions and personal introductions.
At the A2 level, learners expand their use of 'dezasseis' into more complex sentence structures. They should be able to use it in past tense descriptions (e.g., 'Ontem comprei dezasseis postais'). A2 students begin to use the number in compound forms like 'cento e dezasseis' (116) or 'mil e dezasseis' (1016). They should also be comfortable using it with a wider variety of nouns and understanding it in the context of simple directions or schedules. At this level, the distinction between European 'dezasseis' and Brazilian 'dezesseis' becomes more relevant as learners start to notice regional variations in the media they consume.
By the B1 level, the word 'dezasseis' is used fluently in a variety of social and professional contexts. Learners should be able to use it in the 24-hour clock system without hesitation (e.g., 'A reunião está marcada para as dezasseis horas'). They should also be familiar with the ordinal form 'décimo sexto' and when to use it versus the cardinal. B1 learners can use 'dezasseis' in more abstract ways, such as discussing statistics or historical dates (e.g., 'Em mil novecentos e dezasseis...'). Their pronunciation should be accurate, correctly distinguishing the voiced 'z' and the unvoiced 'ss' sounds.
At the B2 level, 'dezasseis' is used in sophisticated arguments and detailed descriptions. Learners can handle the word in fast-paced conversations and complex listening environments, such as news broadcasts or academic lectures. They should be aware of the stylistic choice of writing numbers in full versus using digits in different types of texts. B2 learners also start to encounter 'dezasseis' in idiomatic or technical expressions, such as 'dezasseis avos' in mathematical or legal documents. They can discuss the nuances of the Portuguese language, including why the spelling differs from the Brazilian version, demonstrating a deeper cultural and linguistic awareness.
C1 learners use 'dezasseis' with the same ease as a native speaker. They can identify the word even in poor audio conditions or with heavy regional accents. At this level, the focus shifts to the subtle connotations the number might have in specific cultural or historical contexts in Portugal. They can use the word in high-level academic writing, ensuring perfect agreement and appropriate register. C1 learners are also capable of explaining the etymological roots of the word and its relationship to other Romance languages to less advanced students, showing a mastery of both the word and its place in the linguistic system.
At the C2 level, 'dezasseis' is a tool used for precise and nuanced communication. The speaker can use it in creative writing, poetry, or complex legal discourse where every syllable counts. They have a complete grasp of all historical and regional variations and can switch between them if necessary for stylistic reasons. C2 learners can also appreciate puns or wordplay involving the number and can use it in highly formal or archaic contexts if required. The word is no longer a 'vocabulary item' but a seamless part of their vast linguistic repertoire, used with total confidence and precision.

Dezasseis in 30 Seconds

  • Dezasseis is the Portuguese word for the number 16, specifically used in European Portuguese contexts.
  • It is a cardinal number that does not change for masculine or feminine nouns.
  • Commonly used for age, time (4 PM), prices, and counting various objects in daily life.
  • Distinguished from the Brazilian 'dezesseis' by the 'a' in the middle of the word.

The word dezasseis is the cardinal number representing the quantity of sixteen in European Portuguese. It is a composite numeral, formed historically from the Latin roots for 'ten' (decem) and 'six' (sex). In the context of the Portuguese language, it occupies a specific place in the 'teens' sequence, following quinze (fifteen) and preceding dezassete (seventeen). Understanding this word is fundamental for basic communication, as it appears frequently in daily transactions, age descriptions, and time-telling. It is important to note that this specific spelling, with an 'a' in the middle, is the standard in Portugal, Angola, Mozambique, and other PALOP countries, whereas Brazilian Portuguese utilizes the variant dezesseis with an 'e'.

Cardinal Number
It functions as a determiner or a noun to indicate a specific count of sixteen items or the abstract concept of the number itself.
Age Milestone
In many Lusophone cultures, reaching sixteen marks the beginning of partial legal capacities, such as the legal age for marriage with parental consent in Portugal or the minimum age for certain types of employment.

Comprei dezasseis maçãs no mercado esta manhã.

When using dezasseis, speakers are often referring to measurements. Whether it is sixteen degrees Celsius on a cool Lisbon afternoon or sixteen euros for a lunch menu, the number is ubiquitous. Its pronunciation is distinct, characterized by the voiced 'z' sound and the sibilant 'ss' which remains sharp. In mathematical contexts, dezasseis is the square of four, a detail that might come up in academic or technical discussions. Linguistically, it belongs to the group of numbers from sixteen to nineteen that are formed by the prefix 'deza-' (a contraction related to 'dez' and the conjunction 'e').

O comboio para o Porto parte às dezasseis horas em ponto.

In social settings, dezasseis is frequently heard during birthdays. The 'sweet sixteen' concept exists but is perhaps less commercialized than in the United States; however, it remains a significant year for teenagers. In sports, especially football, a player might wear the number sixteen shirt, or a team might have sixteen points in a league table. The versatility of the word means it is one of the first fifty words a learner should master to navigate basic life in a Portuguese-speaking environment. It is also used in addresses, such as 'Porta número dezasseis', which is vital for navigation and logistics.

Time Telling
Portuguese speakers often use the 24-hour clock. Saying 'dezasseis horas' is the standard way to refer to 4:00 PM in official schedules.

A temperatura máxima hoje será de dezasseis graus centígrados.

Using dezasseis correctly requires an understanding of its grammatical role as a numeral. Most commonly, it acts as a numeral adjective, preceding a noun to quantify it. For example, 'dezasseis livros' (sixteen books). Unlike the numbers one and two, dezasseis does not change based on gender. You use the same form for masculine and feminine nouns. This makes it relatively simple for English speakers to integrate into their speech once the spelling is memorized. It is also used as a substantive when referring to the number itself, such as in mathematical equations: 'Oito mais oito são dezasseis'.

Quantifying Nouns
Placed directly before the noun: 'Tenho dezasseis canetas'. (I have sixteen pens).
Ordinal Relationship
While 'décimo sexto' is the official ordinal for 16th, in informal contexts like street numbers or floor levels, 'dezasseis' is often used: 'Moro no dezasseis'.

Ela faz dezasseis anos no próximo mês.

In the context of age, Portuguese uses the verb 'ter' (to have) rather than 'ser' (to be). Therefore, one says 'Eu tenho dezasseis anos' (I am sixteen years old). This is a common pitfall for English speakers. Furthermore, when dealing with currency, dezasseis is used to denote the whole unit: 'Custa dezasseis euros e cinquenta cêntimos'. Note how the number stays constant regardless of the noun's gender (euro is masculine). In dates, while we usually use cardinal numbers for the first of the month (primeiro de maio), for the sixteenth, we use the cardinal: 'Hoje é dia dezasseis de junho'.

O autocarro número dezasseis para na Praça do Comércio.

In mathematical expressions, dezasseis is frequently used. For instance, 'Dezasseis a dividir por dois dá oito' (Sixteen divided by two is eight). In more complex sentence structures, it can be part of a prepositional phrase: 'Um grupo de dezasseis pessoas'. Here, the number acts as the object of the preposition 'de'. It is also important to recognize it in listening exercises, especially when combined with 'e' (and), such as 'cento e dezasseis' (one hundred and sixteen). The phonetic link between 'cento' and 'e' and 'dezasseis' can sometimes confuse beginners, making it sound like one continuous word.

Compound Numbers
Used as a component in larger numbers: 'mil novecentos e dezasseis' (1916).

Havia dezasseis fatias de bolo, mas agora só restam duas.

You will encounter dezasseis in various everyday scenarios across Portugal and other European-Portuguese speaking regions. One of the most common places is at the supermarket or local 'mercado'. When a vendor weighs your fruit and says 'São dezasseis euros, por favor', they are using the cardinal number to request payment. Similarly, at a 'pastelaria', you might hear someone ordering a specific quantity of cakes for an office party: 'Queria dezasseis pastéis de nata, por favor'. The number is essential for commerce and basic survival tasks.

Public Transport
Listening for gate numbers at the airport or platform numbers at a train station like Santa Apolónia or Campanhã: 'O comboio parte da linha dezasseis'.
Radio and News
Weather reports frequently cite temperatures: 'A mínima para hoje em Bragança é de dezasseis graus'.

Atenção passageiros: o voo para Londres sairá pela porta dezasseis.

In a classroom setting, teachers often refer to page numbers or exercise numbers. 'Abram o livro na página dezasseis' is a phrase every student in Portugal has heard. In the workplace, dezasseis appears in deadlines and schedules. Since Portugal uses the 24-hour clock for official business, a meeting at 4 PM is always a meeting at 'dezasseis horas'. This can be a point of confusion for tourists who are used to the 12-hour AM/PM system. Hearing 'dezasseis' in this context requires a quick mental subtraction of twelve to realize it's late afternoon.

O meu filho faz dezasseis anos amanhã e vamos fazer uma festa.

Socially, you might hear it during a game of Bingo or while watching the lottery results on television. In these high-pressure listening environments, distinguishing dezasseis from sessenta (sixty) is crucial, as they can sound somewhat similar to the untrained ear due to the shared 's' sounds. Furthermore, in historical discussions, you will hear it as part of dates. The year 1916 (mil novecentos e dezasseis) was significant for Portugal as it marked the country's entry into World War I. Thus, in museums or history documentaries, the word is a frequent guest in the narrative.

Sports Commentary
'O remate passou a dezasseis metros da baliza' or 'O jogador número dezasseis entra em campo'.

São dezasseis euros e vinte cêntimos, quer fatura com número de contribuinte?

One of the most frequent mistakes made by learners is the confusion between the European Portuguese spelling dezasseis and the Brazilian Portuguese dezesseis. While both are understood globally, using the 'e' version in a European context can lead to subtle friction in formal writing or academic settings. Another common error involves the pronunciation of the 'ss'. Beginners often forget to pronounce it as a sharp 's' sound, sometimes sliding into a 'z' sound because it is between vowels. However, the double 's' in Portuguese is specifically there to maintain the voiceless alveolar fricative sound.

Spelling: 'a' vs 'e'
Mistake: Writing 'dezesseis' in Portugal. Correction: Use 'dezasseis'. The 'a' reflects the historical contraction 'dez a seis' or 'dez e seis' differently in the two regions.
Phonetic Confusion
Mistake: Mixing up 'dezasseis' (16) and 'sessenta' (60). Correction: Focus on the 'deza-' prefix for 16 and the '-enta' suffix for 60.

Errado: Eu tenho dezasseis de idade. Correto: Eu tenho dezasseis anos.

A grammatical mistake often seen in English speakers is the translation of 'I am sixteen'. Translating this literally as 'Eu sou dezasseis' or 'Eu estou dezasseis' is incorrect. In Portuguese, age is something you possess, not something you are. Therefore, the verb 'ter' is mandatory. Another nuance is the placement of the word in compound numbers. In English, we say 'one hundred and sixteen'. In Portuguese, it is 'cento e dezasseis'. Forgetting the 'e' (and) between the hundred and the teen is a common slip. Conversely, learners sometimes try to add 'e' where it doesn't belong, such as 'mil e dezasseis' (correct) vs 'mil e seiscentos' (also correct), but the rules for 'e' in large numbers can be tricky.

Cuidado: Não confunda dezasseis com dezasseis avos em frações.

Lastly, there is the issue of gender agreement. While dezasseis itself is invariable, some learners get confused because numbers like 'um/uma' and 'dois/duas' change. They might mistakenly try to create a feminine version of sixteen (like 'dezasseisa'), which does not exist. The number remains dezasseis whether you are talking about 'dezasseis rapazes' (sixteen boys) or 'dezasseis raparigas' (sixteen girls). Mastery of this word involves not just the word itself, but resisting the urge to apply rules from other numbers that don't apply here. Practice writing the word multiple times to cement the 'a-s-s' sequence in your muscle memory.

Over-complicating Gender
Mistake: Trying to change the ending of 'dezasseis' to match a feminine noun. Correction: It is always 'dezasseis'.

When exploring the semantic neighborhood of dezasseis, the most obvious related word is its ordinal counterpart: décimo sexto (sixteenth). While dezasseis tells you 'how many', décimo sexto tells you the position in a sequence. Another related term is the fraction dezasseis avos (one-sixteenth), used in mathematics and music (though 'semifusa' or other terms might be used for notes). In certain contexts, you might use 'uma dezena e meia' to mean approximately fifteen, but there is no common collective noun specifically for sixteen like 'uma dúzia' (a dozen) for twelve.

Dezasseis vs. Dezesseis
The primary difference is regional. 'Dezasseis' is the standard in Portugal, while 'Dezesseis' is the standard in Brazil. They are semantically identical.
Dezasseis vs. Décimo Sexto
Use 'dezasseis' for quantity (16 apples) and 'décimo sexto' for order (the 16th apple in a row).

Ele ficou em décimo sexto lugar na corrida, logo a seguir ao número dezasseis.

In informal speech, people might use 'quase duas dezenas' (almost two tens/twenty) to approximate sixteen if the exact number isn't critical. In terms of synonyms, there aren't many for a specific numeral, but you can describe it as 'duas oitavas' (two octaves) in a musical context or 'quatro ao quadrado' (four squared) in a math context. When talking about time, 'quatro da tarde' is the common alternative to 'dezasseis horas'. Depending on the level of formality, choosing between the 24-hour and 12-hour clock changes which word you use.

Podes substituir dezasseis por 'quatro da tarde' se estiveres a falar com amigos.

Other words often confused with dezasseis include dezassete (17) and dezanove (19). All share the 'deza-' prefix, which can lead to errors during rapid speech. It is helpful to practice these as a set to ensure the endings are distinct. In written Portuguese, specifically in literature or formal essays, you might see the number written out to provide a certain rhythm to the sentence, whereas in technical manuals, the digit '16' is preferred. Understanding when to use the word versus the digit is part of mastering the register of the language.

Related: Dezanove
Meaning 19. Notice the 'n' in 'nove' changes the prefix slightly to 'dezan-' in some pronunciations, but it follows the same pattern as 'dezasseis'.

How Formal Is It?

Fun Fact
