The method which is used is on the chart to the right with english equialence and examples to the left, the tense/aspect is done like normally in umbrean verbs
to form modality of various sorts one uses a copula or do verb along with the Verb form as mentioned on the side to turn the verb into adjective or noun and then modifies it. lets give examples below.
Enathtjioyömööluth means "I must sit" or more literly "I am in a temporary state of having to sit". When applied in passive form one treats it simply as an adjective trying to be predicative form.
Novügnu döndikwuu nüëlömööluth means "I must punch the tooth" or more literly it means that you must do it so the tooth is in a must state of being punched. With transitive one uses teh same transformation on the main verb but uses it as an adjective (though lacking the declensions of real adjectives) and uses Nüël, which means similar to "do", nad it is used like a normal verb
