According to Munro, e)orgaj < "weworgas". Presumably this (like leloipa is a perfect formation? In the context (Iliad III.57) it would work fairly well as a stative.
Though I see it all the time, I'm still not sure what's going on here. I thought the stem was "wep", so an aorist formation would be ewep- > eip (as in Attic?). Whence then has come the extra epsilon?
thanks as ever
