This etymology seems to be modelled after the one which is mentioned right afterwards, deriving the word from ἵκω (see ξενός / ἵκω). It seems that we are dealing here with two complementary etymologies, built on the same formal model, and meant to explain two different meanings of ξένος, either "inviting person" (from ἄγω "to lead") or "invited person" (from ἵκω "to come"). The formal derivation is identical : the etymology in either case starts from a future, that is, an inflected form, which provides the sequence [ks], and then implies an apocope of the initial vowel. Apocope was a frequent phenomenon in Oros' time (5 AD), so that it is likely that we can ascribe to Oros not only the etymology deriving ξένος from ἵκω but also the one deriving it from ἄγω, which are two sides of the same coin since they rely on the same formal mechanism and account for the two meanings, active and passive, of ξένος. In that respect, it is not certain whether the intermediate step ἄξενος was equated with ἄξενος "inhospitable" or not (as the semantic relationship between ἄγω "to lead" and ἄξενος "inhospitable" is unjustifiable): it may be a ghost-word invented for the sake of the etymology, parallel to *ἴξενος, and different from the existing ἄξενος "inhospitable"

The first etymology adduced, through σκηνή, is different and may not be by Oros.
