What's my dwarf mumbling about, it's not a material?

Solution 1:

Artifact names are just random compound words, in Dwarvish. If the kid finishes his artifact, you'll find out the intended translation, which very well may be something like "The Beard of Quiet" despite having nothing to do with beards (durad) or quiet (kàs I think, although the accent makes it hard to search for). Since he's a child, he doesn't have any useful skills, so he'll be making some kind of rockcraft (if you're lucky) or wood- or bonecraft (if you're not) object, and you'll find out what it is when he's finished!

Also, what is wrong with a child creating a beard artifact? He needs to keep his beard long and silky somehow!
