This volume, the third in the Studies in Bilingualism series from the EuropeanScience Foundation's research on adult immigrants' L2 acquisition, begins with theobservation that we have widely accepted the idea that learners' varieties and thetransitions from one variety to the next are systematic, yet we have little research that records thissystematicity. This study does exactly that by following for 30 months 10 L2 learners'developing linguistic means for indicating spatial relations. Carroll reports on two Italianspeakers acquiring English; Becker on four Italian speakers and a Turkish speaker acquiringGerman; and Giacobbe, Perdue, and Porquier on two Spanish speakers and a Moroccan Arabicspeaker acquiring French. To elicit the core data, the researchers asked the learners to describepictures and to provide stage directions for a scene they had viewed to someone who had notseen it.
