Accordingly, the virtual absence of this verbal strategy in Nilo-Saharan
languages with a verb- final syntax and its emergence in Nilo-Saharan groups
which are not verb-final, such as Nilotic or Surmic, is nothing but an
incidence of family-specific historical fact.
The actual system of head marking on the verb, whether involving core or
peripheral semantic roles, always depends on the specific history of a language
or language family, with internal as well as external (contact) factors deter-
mining the dir ection of change. There is thus absolutely no un iformity in this
respect between languages that may indeed be claimed to share a verb-final
syntax.
Languages putting the verb in final position may also differ considerably as
to the way in which they express complex clausal relations. Nevertheless, there
seems to be at least one non-trivial morphosy ntactic phenomenon which does
seem to be related to constituent order phenomena, namely verbal com-
pounding. This latter aspect, as argued in section 9.5, would seem to fol low
from the “self-organizing principles” of these languages. Before moving into
this common and widespread morphosyntactic property of so-called verb-final
languages, however, I will investigate one additional property of languages
with this proclaimed syntactic configuration, showing again how different such
languages can in fact be from each other from a typological point of view.
9.4 Beyond the clause level
In an important study on the structure of narrative discourse, Long acre (1990 )
has shown that African languages may differ considerably with respect to the
expression of the storyline in narrative discourse. A common pattern in so-
called verb-final languages of northeast Africa involves the use of converbs,
i.e. of morphologically reduced finite verbs occurring in dependent clauses.
Traditionally, converbs have been referred to by way of a variety of other
terms, e.g. as participles or gerunds. But these labels would seem to represent a
typical translation-oriented nomenclature rendering the pseudo-literal trans-
lation of the form into European languages, rather than recognizing its true
form and function. Crosslinguistically, converbs tend to share two important
characteristics (as established by Haspelmath & Ko
¨
nig 1995). First, such verb
forms are morphologically distinct from main verbs, which tend to carry the
maximum number of inflectional properties, or from other dependent verb
forms, e.g. those occurring in adverbial clauses. Second, the semantic range
covered by thes e converbs includes (an adverbial type of) modification, and the
expression of event sequences. These properties are illustrated mainly for
Omotic languages in table 9.4.
Omotic languages differ as to whether coreferential (logophoric) vers us
disjunctive reference marking for subjects is distinguished on converbs. In
