Noun (assento)

✕Common Mistakes
Sua assento é o 12A.
‘Assento’ is masculine, so the possessive must be ‘seu’, not the feminine ‘sua’.
Seu assento é 12A.
In Portuguese you need the article ‘o’ before the seat code: ‘é o 12A’. Omitting it sounds unnatural.
Seu assento é o doze A.
Seat codes are read as separate characters, not spelled out as words.

Cultural Tip
In Brazil, airline staff often use the formal ‘seu’ when speaking to passengers they don’t know personally. When speaking informally with friends, you might hear ‘teu’ (in some regions) or simply drop the possessive: ‘Assento 12A.’ Seat labels are always read digit‑by‑digit, so 12A is pronounced ‘doze‑A.’
