Would this sentence and "ghaytan SIS net 'aq" be translated the same way? Is there a particular significance to using one construct over the other?
For some reason Klingons prefer to use 'e' 'aqlu' when predicting the weather. But it's not wrong to use net 'aq. Both are accepted as translations on the reverse exercise.
By "for some reason," jdmcowan means Okrand has specifically told us that Klingons tend to do this. It's not something we just deduced by looking at the canon.
