Prose
The word "prose" first appears in English in the 14th century. It is derived from the Old French "prose", which in turn originates in the Latin expression "prosa oratio" (literally, straightforward or direct speech).
Moll (slang)
"Moll" derives from "Molly", used as a euphemism for "whore" or "prostitute". The Oxford English Dictionary lists the earliest usage in a 1604 quote by Thomas Middleton: "None of these common Molls neither, but discontented and unfortunate gentlewomen." The existence of the popular derivative spelling, "mole", likely reflects the word's history as a spoken, rather than written, insult. Popular usage of this spelling can be seen in the name of The Comedy Company character Kylie Mole. Another example can be seen in a poem by Kevin Munro: "'That Dee will have our jobs; she's a fair dinkum mole!'". The author suggests that this spelling doesn't carry the underworld connotations of the much older "moll" variant.
