"What does this all prove7 Zoller's contention is correct. The
language seems to have retained some very archaic structures,
retaining PIE k-, -l~-, g- and -g-. Many. words in Bangani unlike
other IA languages of the region have not witnessed palatalization
defying RUKi Rule. It is difficult to prove at this point whether
this is because of its affiliation to Kenturn language as claimed by
Zoller. However, on the basis of the first-hand data acquired during
these two field trips. it can be said without any prejudices and with
some certainly (sic)that some Western Indo-European language (perhaps
Tokharian) of which we have no knowledge so far. either had a
significant role in substratumizing Bangani or, Bangani itself was
genetically related to this unknown Western IE language. There are
many other features in the language such as existence of O as against
a of I.Ir., pre-verbal auxiliaries (without being a V2 language
system), and post auxiliary negatives that may also be seen as
retentions of archaic structure in Bangani of which traces are only
in Indo-European languages (Abbi 1997 forthcoming).

"Zoller does not explain the presence of a kentum language in India
through an Indian Homeland Theory but as a left-over of a pre-Vedic
Indo-European immigration into India. He claims that the local people
have a tradition of their immigration from Afghanistan. If they
really lived in Afghanistan original?ly, their case (and their
nuisance value for the AIT) isn't too different from that of the
Tocharians, another kentum people showing up in unex?pected quarters.
But if even the Vedic poets could not recall the invasion of their
grandfathers into India (Vedic literature doesn't mention it
anywhere, vide Elst 1999:164-171), what value should we attach to a
tradition of this mountain tribe about its own immigration many
centuries ago? Could it not rather be that they have interiorized
what the school-going ones among them picked up in standard textbooks
of history, viz. the AIT model? Their presence in Afghanistan or in
Garhwal itself is at any rate highly compatible with the OIT. "
