acible is incorrectly written, and should be written as "dignitary" being its meaning:Verb ago agis agere, egi, actum which means do, Act, carry out something, with the suffix - ible always indicating possibility of. Therefore dignitary means that it can be, feasible; only that feasible has another origin because it comes from the verb facio facis facere feci factum and means the same as Aug.
