Formal vs Informal Register in Portuguese

The «tu» / «você» Distinction

European Portuguese has a rich system of address. Tu is used with friends, family, and peers. Você is more formal but less formal than o senhor / a senhora, which is the most respectful form.

Formal Inversions

In formal Portuguese, subject-verb inversion signals elevated register:

Disse o ministro (The minister said) vs O ministro disse
Será necessário rever (It will be necessary to review)

Register Switching

C1 speakers must seamlessly switch registers depending on context. A job interview requires o senhor/a senhora, while a follow-up email to a colleague may use tu or você.

Key Markers of Formality

Formal: subjunctive mood, passive constructions, nominalization
Informal: indicative mood, contractions (*tá* for *está*), slang

Tip: In Portugal, using *tu* with strangers can sound rude. When in doubt, start with *você* and let the other person suggest switching.

Expressions

Tenha a amabilidade de...Would you be so kind as to...
Agradeço que me informeI would appreciate being informed
Venho por este meio solicitarI hereby request
Com os melhores cumprimentosWith best regards
Faz favor, podes...?Can you please...? (informal)
Caro(a) Senhor(a)Dear Sir/Madam

Common mistakes

~~Tu pode ir embora~~
Você pode ir embora / Tu podes ir embora
Mixing «tu» verb form with «você» — must match pronoun to conjugation
~~Obrigado senhor João~~
Obrigado, Senhor Doutor João
In formal PT, titles like Doutor/Engenheiro are expected
~~Eu quero falar com o chefe~~
Gostaria de falar com o responsável
Too direct for formal register — use conditional + softer noun
~~Oi, tudo bem? (in a formal email)~~
Exmo. Senhor, Venho por este meio...
Informal greeting inappropriate in formal correspondence
~~Me diz uma coisa~~
Diga-me uma coisa
Proclisis (me diz) is Brazilian; European PT uses enclisis (diga-me)
