3.2 The Quechuan language family 195
the phonological characteristics of the modern dialects can be derived from the Proto-
Quechua system by assuming regular sound change. A notorious exception is the exis-
tence of a contrast between plain, glottalised and aspirated stops and affricates in Cuzco
and Bolivian Quechua, and of a similar contrast between plain and aspirated stops in
highland Ecuadorian Quechua.
Orr and Longacre (1968) assumed that the three-way distinction between plain, glot-
talised and aspirated consonants had been inherited from an alleged Proto-Quechumaran
through the intermediate stage of Proto-Quechua. Within the Quechuan family, how-
ever, this distinction is limited to the subset of the QIIC dialects adjacent to the Aymara
linguistic area. Lexical correspondences are frequently inconsistent with respect to glot-
talisation and aspiration between dialects and even internally, within the same dialect
(e.g. Cuzco Quechua riku- ‘to see’ but rik
h
u-ri-‘to appear’, both from the same root riku-,
against Arequipa Quechua rik
h
u-, rik
h
uri-). Likewise, it has been shown that the corre-
spondences between Ecuadorian aspirated stops, on the one hand, and Cuzco–Bolivian
glottalised and aspirated stops on the other, are not systematic (Torero 1984). As a result,
the presence of glottalised and aspirated stops and affricates in Cuzco–Bolivian is often
seen as the effect of language contact between these dialects and Aymara, which has the
same contrasts. The expansion of glottalisation and aspiration into the native Quechua
lexicon was partly explained by a mechanism of iconicity elaborated in Mannheim and
Newfield (1982); see also Mannheim (1991: 177–207). Ecuadorian aspiration has been
interpreted as a case of Cuzco adstratum, dating from the short period of Inca occupation,
possibly in combination with a putative legacy of the area’s pre-Quechuan languages.
There is no clear evidence that glottalised and aspirated stops and affricates belonged to
the Proto-Quechua phoneme inventory.
Reconstructions of the Proto-Quechua sound system are given in Torero (1964) and in
Parker (1969b). The differences between the two reconstructions reside in the treatment
of liquids, vibrants and long vowels. Parker reconstructs the consonants *l and *ˇr,
whereas Torero does not. On the other hand, Torero reconstructs vowel length, whereas
Parker only posits short vowels. As it appears now, *l and vowel length were marginally
present in Proto-Quechua; *ˇr wasanallophone of *r,which later developed into a
distinctive phoneme. It is interesting to observe that the palatal lateral *l
y
is a frequent
speech sound, whereas its plain alveolar counterpart l remains marginal in most dialects.
Proto-Quechua has a three-vowel system, consisting of an unrounded front vowel
i,arounded back vowel u and a low central vowel a.Ifalength distinction did exist
at all, it must have been marginal. The phonetic realisation of the vowels i and u was
variable. When adjacent to the uvular consonant q, they were pronounced as mid vowels
[e], [o]. They were high vowels [i], [u] elsewhere. Given the situation in the modern
dialects, it is likely that this allophonic lowering also occurred before clusters consisting
of a resonant (l
y
, n, r) and q, e.g. Cuzco Quechua sunqu [sɔŋqo] ‘heart’; pirqa [pεrqa]
‘wall’.
