Q: What is good advice for designing a horizontal navigation and sub-navigation that needs to be multilingual?

I am about to start re-designing our businesses' navigation and sub-navigation which needs to be multilingual (specifically English, Italian, French and Dutch), as our platform is the same across the 2 countries we operate online in (except the language).

The navigation/sub will be horizontal to sit under the header of our platform.

This is new territory for me, is there any advice that you would give me before I start? Is there anything I need to bear in mind? Are there any great examples out there that really stand out?
