verb or by negation. For example, a few Central Chadic languages (e.g. Hona,
Ga’anda) have a different word order in the perfective (verb-initial, VSO) and
in the imperfective (SVO), and several Kwa languages have a variation
between SVO and SOV with a similar conditioning. For variations in the
const ituent order trigge red by negation, see section 4.12 .
The proportion of subject-initial languages (SOV or SVO) taken as a whole is
roughly comparable to that observed at world level, but the proportion of lan-
guages with a basic SVO order is considerably higher (and the proportion of
those with a basic SOV order considerably lower) among the languages of Africa
than at world level, at least from a strictly numerical point of view (genetically
balanced samples show a higher proportion of verb-final languages).
Heine (1976) argues that a strict dichotomy between an SVO and an SOV
type cannot be held in African linguistics, and that a satisfying account of the
patterns of word-order variation observed in the African languages requires
recognizing four main types, in the definition of which the position occupied
by the genitive modifier and by noun phrases in oblique functi on is more
important than that of the object.
Heine’s type A corr esponds to what is often considered as the “consistent”
SVO type. Languages of this type have a basic SVOX clause-constituent order,
prepositions and, within the noun phrase, all of the modifiers (including the
genitival modifier) follow the head noun. In Africa, this type is found in all
phyla, but it is particularly predominant in Niger-Congo. In particular, virtu-
ally all Atlantic and Benue-Congo languages belong to it.
A minor type , viewed as a subtype of type A, differs from type A proper in
the position of the adjectival modifier: in this subtype, the adjectival modifier
precedes the head noun (but all other kinds of modifiers follow it, as in type A
proper). This subtype is found in a geographically defineable area including
mostly Adamawa-Ubangian languages, but also som e Benue-Congo and
Chadic languages (in particular Hausa).
Type B is defined by the following characteristics: languages of this type have
postpositions; within the noun phrase, the genitival modifier precedes the head
noun, but all other kinds of modifiers follow it; at clause level, type B languages
may have an SVOX order, or an SOVX order, or both. In other words, this type
groups together SVO languages that differ from the “consistent” SVO type in
putting the genitival modifier before the noun it modifies, and SOV languages
that differ from the “consistent” SOV type by putting the obliques after the verb.
The reason for grouping together these two sets of languages and for considering
as irrelevant the position of the object is that
(a) in all languages that have both constituent orders SVOX and SOVX in
complementary distribution, the genitival modifier precedes the noun it
modifies, which makes it possible to explain the emergence of an
