Verb Conjugation

I have a love-hate relationship with conjugating verbs. It's extremely useful in one way, and in another it's very hard for me to learn. The reason being is the irregular things in the conjugation, which seem to plague the most common verbs in any language. Currently I have not written any irregularities in Reisu. I assume verbs that are more natural to be irregular will come out in speaking, when they are easier to pronounce a different way, or something like that. My vision however is that they are still written the "correct" way. So without further adieu, here's a sample of simple conjugation in Reisu.

To Have - Ra Maino
	Present	Past	Future
Basic	Maino	Mainola	Mainofu
Progressive	Mainonu	Mainonula	Mainonufu
Perfect	Mainodu	Mainodula	Mainodufu

So I want to clarify the designations I gave each type of verb in the chart, because I don't use those terms exactly correctly depending on what grammar guide you read. Basic is just that: present, past and future, which is achieved with no suffix for Present, and the suffixes -la and -fu respectively.

The progressive tense is used for continued or habitual action. This is achieved with the suffix -nu.

The perfect tense is for completed action, and has the suffix -du.

Here's a chart of just the suffixes.

Past	-la
Future	-fu
Progressive	-nu
Past Progressive	-nula
Future Progressive	-nufu
Perfect	-du
Past Perfect	-dula
Future Perfect	-dufu
