“le” in french is the masculine definite article“the”. Where “à” in French means “to”. Therefore The phrase “to the” translates to “au” by putting together ''à + le”, . So keep in mind when one is "going to the" remember ''à + le” translates to “au”. Keep practicing and listening to the speaker to catch this.
Yes, you may be right. But English is not my native language and learning a new language - French - and translating in another foreign language it isn't comfortable. Sometime I focus more on how to write the correct answer in English than in French... in this course.
(There is no course for French with using native language.)
If only there was an option to choose which version of English is your native language.
"Je vais au cinéma" does not translate into "I am going to the movie theater" in the "UK English" language.
We don't use "Movie theater" in our language anymore. It is straight up either cinema or pictures. Then again, to be more general you could call it by the company name like "I am going to Odeon" or something.
Because of this, I am having to do multiple translations in my answers and I am not well versed in US English, Canadian English, African English or Australian English.
Note: I am only guessing that Duolingo is a US company so is using US English.
