Do I really need two translations?

The answer to that question is: Yes!

And not only because these countries represent different cultures, but also because the Portuguese language has its own characteristics in each country.

For example, in Brazil we call flight attendants “aeromoças,” while the Portuguese call them “hospedeiras.”
Other examples of different words whose meaning is the same are:

• Academia – Ginásio (for gym)
• Faixa de pedestre – Passadeira (for crosswalk)
• Menina – Rapariga (for girl)
• Menino, criança – Puto (for boy or child)
• Ônibus – Autocarro (for bus)
• Canudo – Palhinha (for drinking straw)
• Suco – Sumo (for juice)
• Misto quente – Tosta mista (for a hot ham and cheese sandwich)
• Pão na chapa – Torrada (for bread toasted on a griddle)
• Trem – Comboio (for train)

Although the language is the same, Portuguese, there are many variations. Thus, the translation must be suitable for the target audience.
