Please be patient

Our volunteers look into many questions every day; sometimes it takes them a little while to answer.

Pro tip: you can rename the thread title with `.tr <thread name>`

Make it descriptive, including relevant context, but also to the point. This way you improve your chances of getting a more relevant and specific answer.

I'm not sure how I can explain this but I found this link that pretty much sums it up

"de le" doesn't exist (at least, it's completely unrelated to the other things you listed)

de + le = du
de + les = des
de + la = de la
de + l' = de l'

Same idea as when to use le/la/les/l'
