[sc. Meaning] you will run away, you will leap away from the door. Contained in this word is the [adjective] ἀργόν , which is swift, and the [adverb] λίαν ["excessively"]. So, he is saying, won't you run away quickly? But they used to call leaps "skips".[1] Aristophanes in Clouds [writes]: "so why don't you have done with it and skip off quickly from the door?"[2]
There is also [the related present infinitive] ἀπολιταργεῖν ["to skip off"].[3]
