"Worf admires Grilka."
Translation:ghIrIlqa' Ho' wo'rIv.
In Klingon, Worf is pronounced wo'rIv. The written Klingon you see in this course and in The Klingon Dictionary shows pronunciation, not spelling. Klingon does not, for instance, have an f sound.
The alternative would have been to have sentences about tam, DIq, and 'erIy, and that just would have been silly.
But I agree that having to learn names like ghIrIlqa' is useless. The course should have kept to a few simple names.
