Was marked wrong for writing 'speaks' instead of 'talks', do they not both mean falar?
Yes, you could have used "he speaks of the..."
Can somebody please explain the concept of do? Obrigado!
Do = de + o
So, "of the" or "about the", etc.
Use "da" for feminine nouns (de + a).
Where is about in the sentence it completely threw me off.
"Falar de = to talk about".
"De" can be translated as "about" in some contexts (such as this one).
Ele fala do tubarão "ao" menina?
"ao" is uased with a masculine noun. (ao meino).
Oh não, eu me referi ao áudio apenas. É assim que eu ouço.
It should be ao meninO. The contraction is used with a singular male.
Why not ele fala do tubarão para a menina?
But it cost me a heart...
I think "He talks about sharks to the girl" could be fine too.
that would be "ele fala sobre tubarões à garota". It is in general sense and Duo states about a specific shark.
