From adlocative case to debitive mood in Lezgic languages
Résumé
A finite modal form with debitive meaning is found in both Kryz and Budugh, most often ending in -u which seems to be the nominal adlocative case marker. Budugh uses the same form as a nominalized, non finite form, while Kryz does not. This seems to indicate that the grammaticalization process by which a case, when added to a verb stem, may come to express modality, does not necessarily imply a nominalized stage followed by desubordination.
