"Queremos hablar español."
Translation:We want to speak Spanish.
I believe both should be accepted since meaningwise they are about the same. Even though talk is used in connotation "talk to somebody" and speak is used more when you are having a monologue. The thing is I don't see an equivalent for both words in Spanish and therefore, what's the difference
If you have a typo that results in a non-word, Duolingo accepts your answer.
But if you have a typo that results in an existing word, Duolingo does not accept your answer.
And Duolingo also knows that there are keyboards that don't have the "ñ" so that's why it accepts "espanol".
