I was reading the Klingon wiki's page on conjunctions today, and read about the seven (eight if you count *'a'* and *'ach* separately) conjunctions of Klingon, and how other conjunctions are expressed by suffixes.

That got me wondering: How is the concept of "whether" expressed in Klingon? How would one say, for instance, "I don't know whether Mike stole my pie"?

chabwIj nIHpu' Mike 'e' vISovbe'
I don't know whether Mike stole my pie.

This is no more unusual than this canonical sentence:

tlhIngan Hol Dajatlh 'e' vISIv
I wonder if you speak Klingon.
