'Ᾱΐδας, -α (tragg.)Derivatives: Άϊδωνεύς (Il.), see Risch 145.Origin: IE [Indo-European] [1125] *n̥-uid-Etymology: An inscription from Thessaly (SEG 16, 380) gives ΑϜιδαν. Thieme's proposal (1952 = Studien idg. Wortkunde 35 -55 that the word derives from *sm̥ uid-, found in Skt. sam vid-, as `das Sichzusammenfinden [of the family in the underworld]' is not correct, as then Άιδ- should mean `Underworld', not the God of the Underworld; but in Homer it is clear that it means the God, e.g. in formulaic δόμον Ἄιδος εἴσω. Also the aspiration is secondary (in Attic, from ὁ Α. (Kamerbeek ap. Ruijgh, Lingua 25, 1970, 307). The other explanation, as *n̥-uid-, `the Unseen', seems the correct one. Lastly Beekes FS Watkins, 1998, 17 - 19, who points out that the replacement of a root noun, first in the nominative (here as final element of a compound), is parallel to φυγή : φύγα-δε. The A- is sometimes lengthened m.c. (it is not lengthened when it is not necessary or impossible as in ῎Αιδόσδε.)Page in Frisk: 1,33-34
