This sentence questionnaire was created by the four members of the research project ‘To break or be broken — A study of valency-decreasing alternations in East Ruvu Bantu languages’. The project aims to study valency-decreasing alternations in Kagulu, Kami, Kutu, Kwere, Luguru and Zalamo, six underdescribed East Ruvu Bantu languages spoken in Tanzania. The questionnaire is based on the lexical verb list published in Haspelmath (1993), consisting of 31 verb meanings, to study the coding of the anticausative-causative alternation. The questionnaire is tailored to the specific linguistic and cultural area of the research project, and is not intended to be of use for every language or linguistic community. The questionnaire is entirely bilingual English-Swahili. TL stands for ‘target language’. {"references": ["Haspelmath, Martin. 1993. More on the typology of inchoative/causative verb alternations.
