Tu

The Portuguese word tu is the second-person singular personal pronoun, equivalent to the English 'you'. However, unlike the modern English 'you', which serves both formal and informal purposes, tu is strictly informal and intimate. Its usage is one of the most complex aspects of Portuguese sociolinguistics because it varies significantly across the Lusophone world. In European Portuguese (Portugal), tu is the standard way to address friends, family members, children, and people of the same age or younger in a casual setting. It implies a level of closeness and social equality. Using tu with a stranger or a superior in Portugal can be perceived as disrespectful or overly presumptive, almost like a breach of social etiquette. In Brazil, the situation is entirely different. While você is the dominant informal pronoun in most of the country, tu is used extensively in regions like the South (Rio Grande do Sul), the North (Pará), and parts of the Northeast and Rio de Janeiro. Interestingly, in many Brazilian dialects, tu is paired with third-person singular verb forms (e.g., 'tu fala' instead of 'tu falas'), which is considered non-standard but is linguistically pervasive. Understanding tu requires navigating these regional and social boundaries.

Informality

Used for close relationships, family, and peers.

Grammatical Person

Second-person singular subject pronoun.

Regional Variation

Common in Portugal, Africa, and specific Brazilian states.

Historically, tu comes directly from the Latin 'tu', maintaining its role as the singular familiar pronoun for over two millennia. In the Middle Ages, Portuguese also used 'vós' as a formal singular pronoun (similar to the French 'vous'), but over time, 'vós' became restricted to plural use or archaic/religious contexts, and new formal structures like 'Vossa Mercê' (which evolved into 'você') took over the formal singular role. This left tu as the primary marker of intimacy. In modern linguistics, the choice between tu and other pronouns is a study in 'Power and Solidarity'. Using tu signals solidarity. In some African Portuguese-speaking countries like Angola and Mozambique, tu is also widely used in informal contexts, following the European model of conjugation. For a learner, mastering tu is not just about memorizing verb endings; it is about understanding the emotional temperature of a conversation. If someone invites you to use tu (often by saying 'Trata-me por tu'), it is a significant sign of friendship and trust.

Using tu correctly involves more than just placing the word at the start of a sentence. In Portuguese, the subject pronoun is often omitted because the verb ending clearly indicates who is performing the action. For example, 'Falas português?' already implies 'Tu'. However, including tu can add emphasis or clarify the subject in a contrastive sentence. The grammatical hallmark of tu is the second-person singular conjugation, which almost always ends in -s in the present tense. For instance, 'Tu cantas' (You sing), 'Tu bebes' (You drink), and 'Tu partes' (You leave). Irregular verbs also follow specific patterns for tu: 'Tu és' (from ser), 'Tu estás' (from estar), 'Tu vais' (from ir), and 'Tu tens' (from ter). It is vital to distinguish these from the third-person forms used with 'você' (você é, você está, você vai, você tem).

Subject Placement

Can be placed before the verb, after the verb in questions, or omitted entirely.

Object Pronouns

When 'tu' is the object, it becomes 'te' (direct/indirect) or 'ti' (after a preposition).

Possessives

The possessive adjectives associated with 'tu' are 'teu', 'tua', 'teus', and 'tuas'.

In complex sentences involving the subjunctive mood, tu also maintains distinct forms. For example, 'Espero que tu possas vir' (I hope you can come). The consistency of the 's' ending in the second person is a helpful anchor for learners. Another important aspect is the prepositional form 'contigo' (with you), which is the fusion of 'com' + 'ti'. You would say 'Vou contigo' (I'm going with you) rather than 'com tu'. In Brazil, even in regions where tu is used with third-person verbs, the object pronoun 'te' and the possessive 'teu' are frequently used alongside 'você', creating a hybrid system that can be confusing for purists but is natural for native speakers. For example, a Brazilian might say 'Você esqueceu o teu casaco?' (Did you forget your coat?), mixing the third-person 'você' with the second-person 'teu'. However, for a student aiming for standard grammar, keeping the 'tu/te/teu' and 'você/o/seu' systems separate is the recommended path. In Portugal, this mixing is much rarer and usually considered a grammatical error. When writing, especially in formal letters or academic papers, tu is almost never used unless quoting speech or writing fiction, as the formal 'você' or 'o senhor' is required for the intended professional tone.

The auditory landscape of tu is a journey through the geography of the Portuguese language. If you land in Lisbon, you will hear tu everywhere—in cafes between friends, in parks between parents and children, and in schools among students. The European Portuguese 'tu' is often pronounced with a very closed 'u' sound, almost like a whistle. In Porto, the northern accent might make the 'tu' sound slightly more forceful. Moving to Brazil, the usage becomes a marker of regional identity. In Porto Alegre, the capital of Rio Grande do Sul, tu is the pride of the 'gaúchos'. They use it with a distinct melodic intonation, often correctly conjugating the verb (Tu vais, tu queres), which sets them apart from other Brazilians. In Rio de Janeiro, tu is incredibly common in 'subúrbio' slang and among the youth, but it is almost always followed by a third-person verb: 'Tu vai lá?' (Are you going there?). This 'Carioca' usage of tu is often associated with a relaxed, street-smart persona.

Portugal

Ubiquitous in informal settings; strictly 2nd person verbs.

Southern Brazil

Cultural marker; often used with correct 2nd person verbs.

Rio de Janeiro

Very common in informal speech; usually with 3rd person verbs.

In African countries like Angola, Cape Verde, and Guinea-Bissau, tu is the standard informal pronoun, mirroring the Portuguese usage but often infused with local rhythmic patterns. In music, especially in genres like Fado (Portugal) or Bossa Nova and MPB (Brazil), tu is the language of the heart. A singer will address a lover as tu to create a sense of private, shared space. For example, in the famous song 'Águas de Março', the lyrics use 'é' (3rd person) but the sentiment is often directed at a 'tu' in spirit. In television soap operas (telenovelas), the choice of pronoun immediately tells the viewer about the relationship between characters. If a son addresses his father as tu, it suggests a modern, liberal household; if he uses 'o senhor', it suggests a traditional or strict upbringing. Therefore, when you hear tu, you are not just hearing a pronoun; you are hearing a social map of the speaker's world, their origin, and their relationship to the listener.

The most frequent mistake for English speakers is the 'Over-Tu-ing' or 'Under-Tu-ing' trap. Because English only has 'you', learners often default to tu in all situations, which can lead to awkward social friction. In Portugal, using tu with a waiter, a doctor, or an elderly person is a significant faux pas. It is seen as 'falta de educação' (lack of manners). Conversely, in Brazil, using tu in São Paulo might make you sound like you are from Rio or the South, which isn't 'wrong' but might feel out of place. Another major hurdle is verb conjugation. Many learners say 'Tu fala' instead of 'Tu falas'. While this is common in Brazil, it is grammatically incorrect in standard Portuguese and will be corrected in any formal or European context. The third common mistake involves the 'te/ti/contigo' cluster. Learners often say 'com tu' instead of 'contigo' or 'para tu' instead of 'para ti'. Prepositions in Portuguese change the form of the pronoun, and failing to do so is a clear marker of a non-native speaker.

The 'S' Drop

Forgetting to add the 's' to the verb (e.g., 'Tu come' instead of 'Tu comes').

Preposition Errors

Using 'com tu' or 'de tu' instead of 'contigo' or 'de ti'.

Inappropriate Formality

Using 'tu' with people of authority or much older strangers.

Mixing pronouns within the same sentence is another pitfall. In Brazil, this is so common that it is almost a dialectal feature, but in Portugal, it is strictly avoided. For example, 'Tu disseste que o seu pai vinha' (You said your father was coming) mixes tu with 'seu' (the possessive for você/ele). The consistent version would be 'Tu disseste que o teu pai vinha'. Furthermore, learners often struggle with the imperative. They might say 'Tu come!' when they should say 'Come!' (dropping the pronoun and the 's'). Lastly, the pronunciation of tu should be a pure 'u' sound, not a diphthong like the English 'too' (which can sound like 't-yoo'). Keeping the lips rounded and the sound short is key. To avoid these mistakes, practice conjugating common verbs specifically for tu and pay close attention to how native speakers from the specific region you are visiting use the word. If you are in Lisbon, watch for the 's'; if you are in Rio, watch for the lack of it!

The Portuguese pronoun system is a spectrum of formality. While tu sits at the most informal end, there are several alternatives that every learner must know. The most prominent is você. In Brazil, você is the standard 'you' for almost all situations, ranging from casual to semi-formal. In Portugal, however, você occupies a tricky middle ground; it is often considered slightly 'cold' or 'distant' and is sometimes avoided in favor of using the person's name or the third-person singular without a pronoun. For more formal situations, Portuguese uses o senhor (the gentleman) or a senhora (the lady). These are essential for talking to elders, bosses, or people in positions of authority. There is also the plural 'you', which in Portugal is vós (though mostly in the north or in religious texts) and in Brazil and most of Portugal is vocês.

Tu vs. Você

Tu is intimate/informal; Você is neutral/formal (PT) or standard informal (BR).

Tu vs. O Senhor/A Senhora

Tu is for friends; O Senhor is for respect and distance.

Tu vs. A Gente

While 'a gente' means 'we', it is often used in dialogues where 'tu' might be involved in the response.

Another alternative is vossa mercê, though this is purely historical and only found in period dramas or literature. In some very specific religious contexts, vós is used to address God or in very formal speeches. For the modern learner, the main choice is between tu and você. If you are in Brazil, stick with você unless you are in a 'tu-heavy' region. If you are in Portugal, start with você or the person's name, and only switch to tu once a friendship is established. Understanding these alternatives is crucial because using the wrong one doesn't just make you sound 'foreign'—it changes the social dynamic of the interaction. In summary, tu is the pronoun of the heart, the family, and the street, while its alternatives manage the professional and respectful spheres of life.
