Lodeen
Lodeen has three aspects : the action begins or will soon begin; the action is being done; the action is over.

We could define them as debutive/prospective, progressive, and perfective aspects, rather than perfective/imperfective.

They are marked by suffixes, -jen, -jol and -jga respectively, and are added to the verb whose final -l has been dropped.
