However, for nominal modification, the role of language-internal variation remains uncertain. This volume represents the first attempt to investigate sign order variability in this domain, examining what shapes the syntactic structure of LIS nominal expressions. In particular, three empirical studies are presented and discussed: the first two are corpus studies...
