The Immortal Language

There is a language amongst the Immortals clans (all of them) that is a beautiful combination of several known languages put together. For now, I have called the language Manchen-ni. The language is not spoken often in the series, but many Manchen-ni words pop up during the story, mostly as nouns. For example, the words Sapir, Krudos, Doushen, and the rarely used fecha are Manchen-ni words.

FYI: Fecha is a Spanish word for the calendar date. It has a totally different pronunciation and meaning in the Immortal world. Immortals prefer a meaning closer to the Portuguese meaning, which is similar to "noise." The Immortal version is not as nice, though.

The language is actually not spoken as much as it was thousands of years earlier (blame the whole Tower of Babel situation on that), but it is still spoken as a common language for those who cannot, or will not, speak English. Many of the "younger" Immortals hardly ever use the language but have heard it enough to understand it. They prefer to use their native languages and English. The twins, for example, start out speaking only German but later become very proficient in English. They recognize Manchen-ni, but do not know it enough to regularly speak it.

The Elders are required to know it, understand it, and speak it. The Ambassador's Guild is not required to speak Manchen-ni, but they must be able to understand it. This also goes for anyone else working with or for the Sapir (the title given to the Guild and the Elders).

So, in summary:

The twins and their Handlers: understand Manchen-in, do not regularly speak it

The Elders: understand it and speak it

Elizabeth: understands it and can speak it

All additional characters in Great Hall: can all understand it, do not regularly speak it

All additional characters outside Great Hall: some can understand it, none speak it

Humans: have no freaking clue about the language...YET...
