Re:which uses the same word for nephew, niece and grandchild. Nipotesm gone mad.

from a biological veiw, you have as much DNA in common with your neices and nephews and you do with your grandchildren. In kinship terms, they are equal relations.

back in the bad old days, where 50% of your children might die before adulthood, and you might never live to see a grandchild, a neice or nephew was as good a relations to share you wealth with.

Remember, you siblings are closer related to you than your kids!
