Children begin single word use after entry into stage 6 of sensorimotor development and the beginning of representational play (McCune 2008;Piaget 1954), a significant fact because this indicates a bodily and emerging mental understanding of the movements of the children themselves and other objects in space and time. This "embodied cognition" (Barsalou 2005) opens children to learning single words that apply to movement and change over space and time. Talmy's (1983) motion event semantics, in particular his analysis of "path" meaning, further allows linkage of children's earliest single words associated with dynamic events to later linguistic development. Dynamic event words express basic space/time meanings in relation to motion events. In English, verb satellites such as : up, down, here, there, out encode meanings related to reversible aspects of temporal and spatial event sequences which will later be syntactically encoded. In other languages these same meanings are expressed as single words of various part-of-speech status. The chapter documents this early congruence of space-time expression, a more general foundation for the varieties of spatial expression seen across adult languages, and for the beginning of word combinations with verbs.
