So these epithets are more informal, whereas the titles would be used in more formal situations like talking to other nations?

I remember in my last game one of my FM's got a trait called indophonos(not sure on the spelling) something to do with beating the Indians in battle, would this have been the kind of thing used as a title? If so I will rely on eb for my titles and just give them epithets, for something extra.

Cheers
