"Worf celebrates his friend's marriage."
Translation:jupDaj tlhogh lop wo'rIv.
Early in the course creating we were approaching the sentences as if all the variations should be available. So we were adding extra accepted translatuons and hints with -'e' even where there was no indication in the English why a -'e' would be appropriate. We later decided that it was better to limit those to where there is some indication in the English that an -'e' would be appropriate. But there are still a few unneeded -'e' hidden in the course. Thanks for pointing this one out.
