Phonetic Variation in South Bolivian Quechua: Dorsal Lenition and Vowel Deletion

Publicado por

Publicado 2025

This article presents a description of two areas of phonetic variation in South Bolivia Quechua, through the analysis of six interviews with bilingual Quechua-Spanish speakers. The first study describes variable lenition in plain and aspirated dorsal stops k q kh qh (e.g., the pronounciation of paykuna ‘they’ as [pajkuna] or [pajɣuna]), and shows that lenition of q is frequent and general while lenition of k kh and qh is more restricted. Lenition of k is found only in a single phonetic context and lenition of kh is found in only a single root, mikhu- ‘to eat’, in the productions of a few speakers. Lenition of qh is general, but less frequent than lenition of q. The second study presents a quantitative analysis of word-final vowel deletion (e.g., chaypi ‘there’ can be pronounced as [ʧajpi] or [ʧajp]), and shows that deletion is more frequent in phrase-final position and in ...

The MINERvA Collaboration reports a novel study of neutrino-nucleus charged-current deep inelastic scattering (DIS) using the same neutrino beam incident on targets of polystyrene, graphite, iron, and lead. Results are presented as ratios of C, Fe, and Pb to CH. The ratios of total DIS cross sections as a function of neutrino energy and flux-integrated differential cross sections as a function of the Bjorken scaling variable x are presented in the neutrino-energy range of 5-50 GeV. Based on the predictions of charged-lepton scattering ratios, good agreement is found between the data and prediction at medium x and low neutrino energy. However, the ratios appear to be below predictions in the vicinity of the nuclear shadowing region, x<0.1. This apparent deficit, reflected in the DIS cross-section ratio at high Eν, is consistent with previous MINERvA observations [B. Tice (MINERvA Collabo...
