The work of the Primitive Hispanic Lexicon (centuries VIII – XII) was presented lastt November in the head office of the Real Spanish Academy.
The work has initially been directed by D. Ramo'n Menéndez Pidal, and written up by Rafael Lapesa with the collaboration of Constantino García. The edition has been carried out by D. Dry Manuel, by the initiative of the Real Spanish Academy and the Foundation Ramon Menéndez Pidal.

The Primitive Hispanic Lexicon is a glossary of the current romance speakings in the Iberian Peninsula between centuries VIII and XII, that means, before the consolidation of the peninsular languages (Castilian, Galician, Portuguese, Aragonese, Catalan). In order to study these speakings there were practically only the materials of conserved notarial documents of that period. This work is, then, an attempt to draw up, from those materials, the prehistory of the lexicon of our present languages born of Latin. It is the first attempt to compile an inventory of the primitive peninsular romance lexicon.
The book has more of 667 pages of lexicon 46 of preliminaries. The graphical forms (words and their variants) studied in the work are altogether 8,520, which are grouped in a total of 4,933 entrances. In each entrance it's given the etymology of the word, the grammar category, the definition (or definitions, if there are several meanings) and the appointments, carefully dated, of the texts in which the studied word was located.
