I added verb conjugation to my conpidgin

So after a little over a week of communicating I now have my first post relating to my language- Neando. This is my Neando conjugation. Let’s give an example verb. Khaoti( To understand ). To take on the past tense we remove the last letter and add -ra as a suffix. So Khaoti to khaotra and for future we add o by removing the last letter so khaoto. But you add za as an infix in between the penultimate and final syllable. So khaozati khaozatra and khaozato. What are your thoughts?
