Résumé
The book compiles and analyzes the body of words and Person Names, attested in the Ancient Near East during the second millennium BC, which are or may be of Indo-Iranian origin. Many have been surveyed by Mayrhofer (1966, 1974) but a number have often been overlooked or mischaracterized as foreign or Kassite.
Horses, horse-riding and weaponry have obviously played a major role in the expansion of Indo-Iranian.
Conspicuous are the gods (Mitra, Aruna, Indar, Nasattiya) mentioned in Hurro-Hittite treaties.
The bulk of Mittani-Aryan has phonetic features similar to those of Indo-Aryan. But some words suggest that another Indo-Iranian language is attested in the corpus and does not have the same phonetic features.
