Actually, Ariel, a peanut (Arachis hypogaea) belongs to the family
Leguminosae (or legumes) and is *not* hard-shelled per se as most real
nuts are - it has a "skin" more than a hard shell like a walnut or an
almond, and is, in fact, not a nut but a rhizome.

And while I don't doubt that Webster's *may* be a more reliable source
than 3rd Rock for *much* information, in this case Webster's is wrong.

Part of this, however, is semantics. I've heard before that
"botanically" speaking a tomato is a fruit, not a vegetable. Yet
clearly, in common usage, a tomato IS a vegetable. :) That being the
case, while I *do* adamantly hold that a peanut is a rhizome, until they
have a rhizome section in the local grocery store, I'll continue to look
for my peanuts in the nut section. :)
