This is the fifth volume in a renowned series edited by Dan Slobin, focusing oncross-linguistic studies of children acquiring their first language. The series is seminal for itsfocus on languages other than English and for addressing the astonishing diversity andcomplexity of the language acquisition task. Slobin notes that, in contrast to Chomskyan modelsthat consider core grammar to be the main topic of interest, the series was conceived with thenotion of showing “how much fruit there is beyond the core” (p. 14). The goal ofVolume 5 is to explore themes that were relatively backgrounded in the others. Specifically,these themes include: typological analysis, semantic systems, phonology and prosody, individualdifferences, and diachronic processes.
