Basic dates: Discussing birthdays

💬 aniversário on its own means birthday, not anniversary. A wedding anniversary is aniversário de casamento.

💬 Dates use dia plus the plain number, not "twelfth": dia vinte "the twentieth", dia três "the third".

💬 o teu works alone as "yours" because it matches the masculine aniversário. For a feminine word, it changes to a tua: a tua casa "your house".

💬 Months take em and are written in lowercase: em maio "in May", em janeiro "in January".

💬 A form of ir "to go" plus a plain verb talks about plans, just like "going to" in English: Vais sair? "Are you going out?".

💬 jantar is both the verb "to have dinner" and the noun "dinner". The same goes for almoçar "to have lunch" and o almoço "lunch".

💬 obrigado follows the speaker: men say obrigado, women say obrigada. Saying yes by repeating the verb, quero "I want", is more natural than a bare sim.

💬 a "at" plus as "the" becomes às, because the word for hours is feminine. For one o'clock it's singular: à uma "at one".

💬 em plus o becomes no. Use na with feminine words: na praça "on the square".

💬 de plus a becomes da, so it's da praça, never de a praça. With masculine words it becomes do: o restaurante do hotel "the hotel restaurant".

🇵🇹 Portuguese people say combinado to seal a plan once the time and place are set. It's friendly and final, like "sorted".

💬 Put até in front of any time to say goodbye: até amanhã "see you tomorrow", até logo "see you later".

🇵🇹 A standard warm sign-off between friends and family in texts and goodbyes. It's not romantic, but it's too familiar for work emails or strangers.
