I come with the best of intentions, I promise you. 😂

Fair enough... you're from the Western hemisphere, and certainly much of what counts as "astrology" in your part of the world is – more or less – "space phrenology".

Nevertheless, I invite you to ask me anything you want.

What sucks about astrology, in your opinion?

Could be. But given its use in forming geographical/ethnic names, like Hindūgān (‘Hindus’/‘India’), the -ān in Ērān is perhaps better understood as a gentilic/nominalizing suffix.

فناجین.
Middle Persian borrowings are often pluralized with -āt, but apparently -āt doesn't work for words like finjān or sirdāb.

Interesting observation.
This is an unpopular opinion, but I genuinely believe the first of those correspondences (ž > z) is an oversimplification.

Is it najrib or njarrib?
The latter would be Gulf—where I believe it's also common to employ the singularized form of a first-person plural.

Sounds interesting. Go for it!

Pronunciation matters... especially during invocations.
