In ancient Greek, the imperfect is more common than the aorist for this verb, even when the movement is accomplished without any problems or events narrated before the movement is finished. However the aorist can also be used, often without any clear reason for the choice. In Hellenestic Greek, that trend continues in Atticizing authors, but koiné writers start treating this verb like more punctual verbs, using the aorist unless there is a special reason--iteration, conative force, etc, to justify the imperfect. But my main question is about demotic Greek; is it normal to use the imperfect, hgen, simply to narrate a simple, completed act of leading, or has the aorist maintained its koiné dominance? The English verbs "feel" "ache" etc form a similar class of verbs where the usual rules of tense choice do not apply.
