I wrote a few entires from Robert Leckie's World War II memoir, Helmet for My Pillow, over the summer, and there were some words in there that I'll be writing about in the next week or so. From a passage about time he spent in the Marine brig in Australia:
Back in your company, you are a dead man for five days. Even your bunk is denuded of pad and blankets. You are a cipher -- the scapegrace whose picture is turned to the wall.
The OED defines scapegrace as: "A man or boy of reckless and disorderly habits; an incorrigible scamp. Often used playfully."
The etymology: "Scape v. + grace n., the etymological notion being ‘one who escapes the grace of God’. Compare with the older scapethrift and want-grace."
A scapethrift is a spendthrift. A want-grace is "one who lacks grace, a reprobate."
Scape is an "aphetic variation of escape. Frequent in prose use till near the end of the 17th century; subsequently only archaic and poetic, and often written 'scape."
