It is someone who weaves things, for instance, tapestries or carpets. One of the most famous examples may be found in the Greek myth about Arachne who boasted that her skills were greater than those of the goddess Athena.
I don't think there are a lot of weavers in Germany today, but "Weber" is a very common family name (surname) in Germany! The family name comes from the profession and is pronounced the same way, so you might need it once in a while a address a Herr oder Frau Weber! ;)
I think, instead of teaching all the words about a subject, the less frequently used words should be moved for later stages. Now i can't remember many of the words in occupation section.. at least give us the right of bypassing some tests duo..
@djurodrljaca: I left the Incubator 4 months ago, so I'm the wrong person to address :) But it probably won't do to contact the other contributors either since they aren't likely to have more luck with removing this word than I had.
