"We run and you jump."
Translation:maqet 'ej SuSup.
It would not. The conjunction je (note there is no qaghwI') is used to combine nouns. These are verbs (even full sentences really). 'ej (this one does have a qaghwI') is used to combine verbs or sentences and appears between the sentences instead. It can be confusing since English only has one version of "and", but in Klingon they are quite distinct and cannot be substituted for each other.
