Correct derivational etymology, provided as a parallel to a similar derivation. The series of parallels quoted is in fact heterogenous. As a matter of fact, the first three verbs (λιπῆναι, from λιπαίνω, μιῆναι, from μιαίνω, χλιῆναι, from χλιαίνω) are aorist stems matching present stems having themselves a nasal suffix, but the subsequent ones are aorists matching present stems without any nasal suffix (θλιβῆναι, from θλίβω, τακῆναι, from τήκω, στυγῆναι, from στυγέω). In the first sub-series, the infinitive suffix is not -ναι as in the second sub-series, but -(σ)αι. However, in synchrony, the aorist is in -ναι, and that was enough for Greek grammarians. In the wording of the Epimerisms, the aorist of the first sub-series is replaced by a present, which makes the consistency of the series less clear. The aorist form is found in the Et. Gudianum and Magnum, and this probably was the older wording
