just finshed "spanglish" by Ilan Stavans.
has nothing to do with the adam sandler movie
(which i like, incidentally)
this particular book is an analysis of the blending of the two language both north and south of the rio grande, with a peek into how spain feels about it all... as if we care.
interesting for those into the two languages, or any one into border cultures / assimiliation issues at all.
