Say what?

That's exactly what I said when I first espied the word "pertainyms" while wandering around the web.

What the heck is a pertainym?

I mean, it's a cool word and I can sort of figure it out but I can't be certain on my own.

So I had the crack research team drop everything to investigate — I get like that sometimes when a new word drops in.

Anyhow, it turns out that the website I stumbled across was the WordNet 1.7 Vocabulary Helper.

Plenty more there where pertainym — which, by the way, means "meaning related to or pertaining to" — comes from.

Like "hypernym" — there's one to conjure with.
