"Is this a knife?"
Translation:taj 'oH'a' Dochvam'e'?
Close. A very literal translation would be taj 'oH'a' jIH tlhopDaq Doch'e' vIleghbogh Is the thing which I see before me a knife?
A smoother translation, not trying to copy the English syntax, might be jIH tlhopDaq taj vIlegh'a'? Do I see a knife before me?
Perhaps the best fit for the language, but not similar to the original English, might be jIH tlhopDaq tajHey vIlegh I see an apparent knife before me.
