I have said, "I don't believe "bi" has any links to the verb "buudan"". This implies that I don't know for sure. If I knew one way or another I would have provided a clear cut answer. This is why I suggested that fdb would be the best person to answer as he has the expertise and knowledge in this and other linguistic fields.I’m sure the question I asked has been considered/asked before and has been dismissed as implausible, does anyone know if it has been & why it is implausible?
The Verbal Particle BE in Middle PersianAs an adverb BE mostly appears in combinations, in NP bīrūn < MP bērōn ‘outside’, in MP also bēdom ‘furthermost, outermost’ (e.g., inDk6 1 §215, 216), and in bē az ‘outside of’ (e.g., in ŠNŠ 3 §20), az bē ‘from outside’ (e.g., in ŠGW 3 §24; 8 §45, §49), and bēdendar ‘outside’ in MPM (cf. Durkin-Meisterernst 2004: 121). Very common in MPZ is bē ō ‘forth to, away to’.
I am sure you are right but there's nothing wrong with coming up with other theories, as long as they make some sense. Speaking for myself and for others I have come across, academic qualifications are over rated.The way forward is to look at what the scholars in the field have said and then come up with plausible theories if no satisfactory answer is found in their writings.
No comment.If they did n't, they would have made their living by some other means
I agree & I have said as much myself:I don't think you can do this kind of work just by sitting behind a computer.
and who has performed their research on the ground i.e. in various Persian speaking regions
I will certainly look at Gilbert Lazard works on this topic and other Persian matters, personal recommendation is the best method forSome of these scholars have devoted their lives in their academic fields. I have been in touch with Gilbert Lazard (in 2006) amongst others. Lazard died in 2018.
