I decided to make a 2×2 system of verb stems and personal endings to form the four fundamental moods of Denkurian. The verb stems are called direct and indirect, whereas the personal ending sets are called primary and secondary. The various combinations yield moods thusly:

direct + primary = indicative mood
direct + secondary = imperative mood
indirect + primary = subjunctive mood
indirect + secondary = optative mood

This simplifies verb formation just a bit. Also, the following words were added to the lexicon:
zapto – n. weapon, arm (armament)
zeina – adv. always
zezeina – adv. forever, evermore
