adjc. | -ον | δέχομαι
71.5 · Mode · Possible, Impossible
impossible pertaining to not being possible, in the sense of not being in accord with human experience In view of the double negation in LUK 17:1, it may be better to translate ‘things that make people fall into sin are bound to happen.’ The derivative meaning of ἀνένδεκτος in the context of LUK 17:1 is thus a matter of inevitability as based upon human experience (see 71.38).
