French language Q&A Forum

I am trying to figure out how to say "I am good/bad at (something)" in French. There seems to be discrepancies between sources online about what prepositions to use.

For example, I searched "I am good at piano" on an online translator. It gave me many options: Je suis doué pour piano, je suis bon au piano, je suis bon en piano, and je suis doué en piano. I know that you use different prepositions depending on what adjective is used (doué vs bon), but why does this translator give so many options, and which ones are correct?

Also, for example, to say "I am bad at guitar", the translator says you can say either je suis mauvais à la guitarre OR je suis mauvais en guitarre. Which one of these is correct?

Basically, which of these prepositions (en/au/à la/pour) do you use when saying je suis nul/mauvais/bon/doué AT something?

Thank you!

Can you please explain why "J'ai les jeux marron" is not "marrons"?

In the test, I got the following question

"Elle a mangé tout le gâteau !" means:

- She is eating all the cake!

- She ate all the cake!

- She is going to eat all the cake!

- She has eaten all the cake!

- She had eaten eat all the cake!

Could you please explain why we you believe 'she has eaten all the cake' is correct but not 'she had eaten all the cake'? How would we say she had eaten all the cake in French and why is this not passé composé?

In the sentence, "So, let's raise our glasses to the ones [whom] we love and to the future!", love was translated using aimer.  I chose adorer, which was not accepted.   I get this wrong all the time.  Generally, the problem is how to translate love versus like.  With regard to adore, is it that one adores something and not someone ?  Thanks in advance. 

The stone question was not easy. How would one say "Stone collection" or " Pierre's Stone collection"?

Thank you, Di

I received a question to translate "You're laughing while looking at me." where the correct answer is "Vous riez en me regardant." 

Doesn't regarder mean "to watch" and voir means "to see"?

Wouldn't "looking" in this case mean "en voyant"? 

Thank you for your help. 

I understood that the french for ' an app' was 'une appli' but this wasn't given as an option. Am I incorrect?

What is the difference between j'ai vingt and and je suis grand considering they are both followed by a consonant that is not h

pourquoi on utilise 'règnent' ici, pas 'règne' ?

Si triste, mais si vraie.  En mort, apres les combats, les combattants, autrefois ennemis, ont plus en commun que leurs frères en la vie.
