The prefix of the Greek verb is pyro, which of course we still use to refer to burning: pyromaniac, pyrotechnics, etc. And in European languages the influence of the idiom still survives: "burning with curiosity", "that burns me up", etc.

Who woulda thunk it? Old-fashioned philology relevant on MaleSurvivor? What's next? \:D

Much joyous word-crunching,

Nobody living can ever stop me
As I go walking my freedom highway.
Nobody living can make me turn back:
This land was made for you and me.
(Woody Guthrie)
