Hadron,from greek 'qpov - thick ,stout

They were apparently going for: Greek: ἁδρός, hadrós, "stout, thick"

You beat me to it, Darth
There is a neuter noun for it as well: hadron, just like the title

Yes. And it's with ' . That's like H, in Hadron. Thank you, greekos freakos : )

I've never been called a greeko freako before. I love it
