"How old is Azetbur?"
Translation:ben 'ar boghpu' 'a'Setbur?
Students of Klingon have been asking that for a long time, but that's just how Klingons do it. The question word 'ar follows the thing being quantified even though most answers would put the quantifier in front of the thing being counted. This rule was taught in the Tips & Notes of the Counting 1 Skill.
