"Est-ce que l'on peut ..."

Question

One possible translation heer is given as "Est-ce que l'on peut aller prendre un café? "

Is the "le" at all related to the café as direct object? Could you explain/provide examples of other uses of "l'on" in such contexts? Merci en avance!

I found the above link by simply searching for l'on in previous posts  --  I hope you will find this helpful.

Answer

Jim's right, but just to state the reason clearly: the l' in l'on is purely to avoid the harsh sounding "qu'on" in favor of the more flowing "que l'on". It carries no grammatical meaning.

Answer

That l' it's not "le". On is sometimes preceded by l’ for reasons of euphony. It's just something to keep the "e" in "que" and the "o" in "on" of connecting. It's formal and much more common in writen French.
