Did you know?
- While oi is a common way to say 'hi' in Brazil, it is a completely different word from the English interjection 'oi', which is used to get someone's attention.
- In very informal settings, Brazilians may replace the greeting oi with a short, melodic whistle or a specific hand gesture to acknowledge a friend from a distance.
- The word alô is a loanword from the English 'hallo' and is used almost exclusively for phone conversations in Brazil.
