Sorry. This is more Latin to English

That would be an English to Latin translation.

"I am, I was, I will be forever." = sum, eram, ero semper.

Not sure what you mean by "turns" for the other one.

Oops. Sorry...

By "turn" I just sort of meant a change in general. It's hard to explain. You know how, in English, "turn" is used metaphorically to mean any kind of revolutionary change. Think of the word one might use for the change of seasons or something like that. The most precise English words I can think of are "transformation" or "revolution".

Sorry for the confusion. Thank you very much for your help.

Ok - I thought that might be it, but I wasn't sure.

I think:
