Klingon uses intransitive verbs (verbs of being, which require no object) in three ways.
When using these to be verbs as verbs in a sentence, they do not need an object. Only one of the four prefixes indicating no object, namely:-
Su- you (plural)
When the subject is he, she, it or they, no prefix is used at all.
jIbergh I am irritable
jInaS I am vicious
bIchech You are drunk
bIDal You are boring
Daj He is interesting
Doj She is impressive
jej It is sharp
As adjectives, 1
When used to describe someone or something, e.g. interesting situation, unnecessary pleasure, the adjective follows the noun.
jagh Dal a boring enemy
tlhIngan bergh the irritable Klingon
tera’ngan QeH The angry Terran
As adjectives, 2
When used to describe something along the lines of the enemy is interesting, the adjectival verb comes before the noun and takes no prefix:-
bergh tlhIngan The Klingon is irritable
naS tlhIngan The Klingon is vicious
