To express that someone should or ought to do something — not because it is required, but because it is the right, wise, or honorable thing — Klingon uses the verb tlheb ("urge"). The activity being urged is the object of tlheb.

The construction follows this general pattern:

S 'e'/net tlheb

Where S is a full sentence expressing the action that is being urged, where the person being urged is the subject of the first verb. Most often, the subject of tlheb is "I" or "you," but a third-person subject is also possible.

• qagh vISop net tlheb - I should eat gagh. (It is urged that I eat gagh.)
• qagh DaSop 'e' vItlheb - I think you should eat gagh. (I urge that you eat gagh.)
• qagh vISop 'e' vItlheb - I know I should eat gagh. (I urge myself to eat gagh.)
• jISop 'e' Datlheb'a' - Should I eat? (Do you think I should eat?)

Note: You do not say something like qatlheb to mean "I urge you." The object of tlheb is the activity, not the person.
