I don't think 'ladder' is appropriate as this is about people. Perhaps conductor or leader.
You're thinking of "der Leiter".
der Leiter = the leader
die Leiter = the ladder
Would it then be "die Leiterin" if talking about a female leader?
Is this a German idiom? I am not sure why someone would speak this sentence.
Its an odd sentence, but not impossible to work into dialogue "What is a device I can use to get me onto the roof?" "Well, the ladder is one..." or alternatively, "what is a word that is likely to confuse german students?" "Die Leiter is eins"
Yes, but the section is all about learning the names of professions. So it's completely out of context here.
Maybe, but its probably a good idea to learn similar words at the same time as we learn professions so that we don't get confused later on.
I would accept that, except that they titled the section "Professions" so I find it much more confusing this way, but I guess it comes down to personal preference.
Yes, this is a very strange sentence given that it's in a section about learning the names of professions.
What does it supposed to mean, 'The ladder is one'?
It doesn't make sense to me at all.
are questions like this just here to trick us?
