How do Portuguese speakers answer the phone?
Hello was supposedly used for the first time around 1877:
The word "hello," it appears, came straight from the fertile brain of the wizard of Menlo Park, N.J., who concocted the sonorous syllables to resolve one of the first crises of techno-etiquette: What do you say to start a telephone conversation?
Some attribute hello's origin to a derived form of hola. However, I don't remember hearing native Portuguese speakers saying olá in order to start a telephone conversation (not as the first word at least).
These are the expressions I have heard so far from Brazilian people:
- allô?
- oi!
- [organization's name] bom dia/boa tarde/boa noite
And from Portuguese people:
- está lá? (I'm assuming it means: "are you there?")
- estou sim? (this one I'm not sure, does it mean "I am here, yes?"?)
- sim?
- allô (not as often as Brazilian people though)
- [organization's name] bom dia/boa tarde/boa noite
If there are more expressions besides these ones, I would like to know where they are used (locations/regions) and their context.
Finally, why is the French word "allô" used in Portuguese?
