Ravid & Tolchinsky's paper draws a comprehensive picture of the fact that literacy is a lengthy developing process involving many linguistic factors which sometimes begins even before school age and lasts until adulthood. I very much appreciated the breadth and thoroughness of Ravid & Tolchinsky's paper and, in particular, the fact that they have taken the relationship between oral language and literacy into account. It seems to me that this is rarely the case in current linguistic theories and I would like to offer a few comments on some of the consequences that a serious approach to literacy development would have on the studies of both oral language and literacy, and on linguistic theories themselves as well.
