On: Why do old books smell so good?

[logdahl]

I would say it translates to old book smell

[hoyd → logdahl]

Yes, that would be it. The word "gammel" means most of the times old, but I can see where it would be used as something rotten too.

[mjochim → hoyd]

In Scandinavian languages, gammel or a similarly-spelled cognate means "old". I dont know about rare cases where it might mean "rotten", I dont speak any of them well enough. But in German, "gammeln"/"vergammelt" doesnt mean old. It means to rot/rotten.
