Both headword and gloss are in the neuter singular. The entry is taken from the Synaagoge or Photius, where it occurs identically. Its origin is probably Hesychius, Lexicon delta2533: δυσαχθὲς: βαρύ . That entry in Hesychius is considered by K.Latte a Cyrillian interpolation, which is probable considering that the same gloss occurs (according to Latte) in two Cyrillian codices still unpublished: Laurentianus 57,39 and Coislinianus 394. On the other hand one should take into account the fact that this adjective (intensively used only in Patristic texts, Cyrillus especially) is unattested until the second century AD -- when we find it in Maximus Astrologus (in reference to illness), in Aretaeus (medical literature), Tryphiodorus (poetry) and Cyranides (magic) --, and that Hesychius’ sources, through Diogenianus and others, are mainly writers of the classical and Hellenistic periods.
