Translation of besides

Question

My dictionary gave me two choices: de plus and en plus.  Qui plus est was not even a choice.  I always seem to make the wrong choice.  Can someone explain the nuances of the translation of besides?

Accepted Answer

Hi Frank,
When 'besides' means 'in addition to this', it will be translated as 'en outre', 'de plus' and we give you 'qui plus est' (lovely expression).
I would say that 'de plus' is the most common way to translate 'besides' in this instance.
Bonne Continuation !

Answer

The translation of "besides" in the sense of "in addition to", could be either "de plus de" as well as "en plus de". As I see it, they are both synonymes.

Answer

So d'ailleurs, (which also means besides, and which I used), shouldn't be used in this context? Why?  Thank you for any answer. E
