I was wondering whether we can pack into a single klingon sentence, the question:

"When did you buy the phone, which you now use ?"

If we translated it exactly, then perhaps we would have:

{ghorgh DaH ghogh HablI' Dalo'bogh Daje' ?}

But the existence, side-by-side of {ghorgh} and {DaH}, results in an awkward sentence
