This is really confusing: If someone says, "I bought a shirt for him" or "I bought a shirt from him." Do both of these get translated to:

Je lui ai achete une chemise

Please enlighten me. Thank you!

Hi, at the end of each lesson there is this “Examples” section. But it only contains the sentences/phrases that are mentioned in the lesson: they are not new and so, they are not helpful. Is it possible to improve this section and make it contain new examples so that we can manually test ourselves?

Why is there no listening in this listening excercise? I feel like you people need to fix this 

As an alternative to "des aiguilles de pin," can one write "d'aiguilles de pins"?  Or is "des aiguilles" appropriate because (as I suppose is the case)
"aiguilles" are considered uncountable here?  And why "de pin" instead of "de pins"?

So, for words that end in -re, we drop the "d" as well?

There is really no explanation of how to distinguish when to use these properly.

In the first line, Le pourquoi du comment translates to the whys and hows. Shouldnt le pourquoi du comment be "The why of the how". Please explain the difference between these things. Merci 

I don’t understand the purpose of “t” here as the verb is not reflexive. All these are equivalent but I’m at a loss of the use of “t-on” . What lesson would help with this?
