this second slot Kimbu and Nilyamb a have Far Past #al
I
which might be a
reduced form of the Sukuma/Nyamwezi -al
I
‘past þ be.’ The Nyaturu evi-
dence for this shape is shaky; in one Nyaturu dialect it is said to carry the same
function as (low-toned) na
`
a Near Future in the main dialect. But it is high-
toned na
´
a in this second dialect which means Far Past: maybe this is a mistake
in the data? Furthermore this ali¼ari is not unique to our languages, being
widespread in the meaning Far Past in many eastern Bantu languages, as can be
seen in the examples in (7) and (8), taken from languages adjacent and to the
southwest of our target languages.
Similarly with other parts of the preverbal complex. Nyaturu (a
´
ja) and
Nilyamba (aza) have a cognate preverbal Near Past, which probably derives
from “pastþcome,” a common enough form of gramm aticalization, but not
attested in Kimbu or Sukuma/Nyamwezi. Finally, Nilyamba and Kimbu have a
Persistive morpheme -kyal i-, which can plausibly be analyzed as -k
I
þpastþbe.
While this -k
I
- might relate to the k
I
I
“persistive” of Nya turu, it should be noted
that Nyaturu -k
II
comes in the final preverbal slot, not the initial one, and that
this k
I
(
I
) is not attested in Sukuma/Nyamwezi.
All this detail can be summarized thus. We would like to see a solid set of
categories and morphology in Nilyamba and Kimbu similar to those that occur
in the Nyaturu preverbal complex. While there are minor similarities, and
maybe some shared innovations, the evidence for such a set is simply not there,
and its absence is unlikely to be due to lacunae in the data.
On the other hand, in order to prove the preverbal clitic cluster to be an
internal development, it would also be necessary to demonstrate reas onably
that the Nyaturu preverbal complex is a reduc tion of structures inherited from
the earlier link with Sukuma/Nyamwezi. It should be possible to show that
Sukuma/Nyamwezi has the auxiliary structures that could have been fused to
produce something like what we find in the preverbal complex in Nya turu.
Sukuma/Nyamwezi is very rich in auxiliary structures. We have counted
several dozen structures, most involving two verbs, a few involving three.
Further, as suggested in (5) and (10), Sukuma/Nyamwezi does fuse auxiliary
and main verbs. But with a few exceptions, all Sukuma/Nyamwezi auxiliaries
are forms of ‘be’ (either –l
II
or -
iiza). They do not resemble the morphemes
exemplified in (4). And considering the reduction processes current in
Sukuma/Nyamwezi, indeed, considering any reduction processes, it is hard to
imagine how most of the components of the Nyaturu preverbal complex might
derive from anything in contemporary or older Sukuma/Nyamwezi.
The evidence does not support the hypothesis that the preverbal complex can
be directly derived from inherited structures. It suggests strongly the adoption
of the basi c preverbal structure, or at least large parts of it, from a neighboring
West Rift language. The structure itself can be interpreted as a transfer, the
constituent morphemes are a mixture of inherited and transferred items, the
