Genitive singular is -εος (δίπηχυς also as in ἥμισυς) Smyth has example only for oxytone like ἡδύς, βαθύς, βραχύς. Normally compounds of -βραχύς are given with masc.neut.genitive.singular -εος (δίβραχυς#Bailly@ΛΟΓΕΙΟΝ) but oddly, the same dictionary gives -εως (for genitive?) ἀμφίβραχυς@Bailly@ΛΟΓΕΙΟΝ. Does anyone know why? Thank you ‑‑Sarri.greek ♫ | 08:53, 30 October 2021 (UTC)
