The endings are generally those of the Active voice with a characteristic Middle voice -o (sometimes -e), in which the basic form is relegated to the secondary endings, while it becomes the Primary by adding an -i.

In the Moods, the endings are usually the same, but there are some exceptions. As in Indicative -a- / Subjunctive -a-, where sometimes the first singular Subjunctive is -ai. Generally, though, the adding of the Middle voice secondary endings is enough.
