Changes

If the aorist stem is different from the present stem (i.e. the verb is irregular) then the aorist stem is used, but the present endings are used. For example, the verb [[ερχομαι]] (I come) is irregular, with the aorist principle part as [[ελθονηλθον]] (I came). Hence this is a second aorist verb, and the ''aorist, active, nominative, masculine, singular'' form is '''[[ελθων]]''' (not ελθσας - which doesn't exist). Note that the augment of '''ηλθον'''' is removed in '''ελθων'''.
