Greek legend gives indications on the subject of language at Troy. For one thing, the allies of Troy, listed at length in the Trojan Battle Order which closes book 2 of the Iliad, are depicted as speaking various languages and thus needing to have orders translated to them by their commanders. Elsewhere in the poem they are compared to sheep and lambs bleating in a field as they talk together in their different languages. The inference is that, from the Greek point of view, the languages of Trojans and their allied neighbors were not as unified as those of the Achaeans.
There was not enough evidence to fruitfully speculate upon the language of Troy until 1995, when a late Hittiteseal was found in the excavations at Troy, probably dating from about 1275 BC. Not considered a locally made object, this item from the Trojan "state chancellery" was inscribed in Luwian and to date provides the onlyarchaeological evidence for any language at Troy at this period. It indicates that Luwian was known at Troy, which is not surprising since it was a lingua franca of the Hittite empire, of which Troy was probably in some form of dependency. Another sphere of research concerns a handful of Trojan personal names mentioned in the Iliad. Among sixteen recorded names of Priam's relatives, at least nine are not Greek and may be traced to "pre-Greek Asia Minor". On this basis Calvert Watkins in 1986 argued that the Trojans may have been Luwian-speaking. For instance, the name Priam is connected to the Luwian compound Pariya-muwa, which means "exceptionally courageous". Additionally, the Alaksandu treaty describes Mira, Haballa, Seha and Wilusa as the lands of Arzawa, although this "has no historical or political basis", suggesting that it was the language that they had in common. Frank Starke of the University of Tübingen concludes that "the certainty is growing that Wilusa/Troy belonged to the greater Luwian-speaking community". Joachim Latacz also regards Luwian as the official language of Homeric Troy, but he finds it highly probable that another language was in daily use. Ilya Yakubovich provides a critical evaluation of the arguments by Watkins and Starke in his University of Chicagodissertation and concludes that the ethnicity of the Trojans remains completely unknown.
