In this changeset, I actually also removed etymology tags. The reason is that they repeated the etymology for generic geographical terms (“guelta”, “sebkha”) over a hundred times and provided no information on the namesakes of individual objects. Systematically, this pretty much amounts to giving the etymology for the word “river” on every single river. See the wiki for the etymology tag: https://wiki.openstreetmap.org/wiki/Key:name:etymology

For ease of reference, these are the tags which I removed:
