to be a centum language and thus closer to Greek. The reason that in the past Phrygian had the guise of a satəm language was due to two secondary processes that affected it. Namely, Phrygian merged the old labiovelar with the plain velar, and secondly, when in contact with palatal vowels /e/ and /i/, especially in initial position, some consonants became palatalized. Furthermore, Kortlandt (1988) presented common sound changes of Thracian and Armenian and their separation from Phrygian and the rest of the palaeo-Balkan languages from an early stage. Modern consensus regards Greek as the closest relative of Phrygian, a position that is supported by Brixhe, Neumann, Matzinger, Woodhouse, Ligorio, Lubotsky, and Obrador-Cursach. Furthermore, 34 out of the 36 Phrygian isoglosses that are recorded are shared with Greek, with 22 being exclusive between them. The last 50 years of Phrygian scholarship developed a hypothesis that proposes a proto-Graeco-Phrygian stage out of which Greek and Phrygian originated, and if Phrygian was more sufficiently attested, that stage could perhaps be reconstructed. Recent migration hypotheses Some scholars dismiss the claim of a Phrygian migration as a mere legend, likely arising from the coincidental similarity of their name to the Bryges, and have theorized that migration into Phrygia could have occurred more recently than classical sources suggest. They have sought to fit the Phrygian arrival into a narrative explaining the downfall of the Hittite Empire and the end of the high Bronze Age in Anatolia,. According to the "recent migration" theory, the Phrygians invaded just before or after the collapse of the Hittite Empire at the beginning of the 12th century BC, filling the political vacuum in central-western Anatolia, and may have been counted among the "Sea Peoples" that Egyptian records credit with bringing about the Hittite collapse. The so-called Handmade Knobbed Ware found in Western Anatolia during this period has been tentatively identified as an import connected to this invasion. Relation to their Hittite predecessors Some scholars accept as factual the Iliad'''s account that the Phrygians were established on the Sakarya River before the Trojan War, and thus must have been there during the later stages of the Hittite Empire, and probably earlier, and consequently dismiss proposals of recent immigration to Phrygia. These scholars seek instead to trace the Phrygians' origins among the many nations of western Anatolia who were subject to the Hittites. This interpretation also gets support from Greek legends about
