Speaking as someone with an
ambition of going to Germany to work as an entomologist, I find this really useful.
Aber... jedes Insekt hat sechs Beine (except those who lost some of them accidentially). So you wouldn't say exactly this as an entomologist.
Idiomatically, in English, this could mean all insects have six legs (imagine someone saying, "the insect, now, has six legs.") Could it mean the same in German?
