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).
Controversy
Controversy is a state of prolonged public dispute or debate, usually concerning a matter of conflicting opinion or point of view. The word was coined from the Latin "controversia", as a composite of "controversus" – "turned in an opposite direction," from "contra" – "against" – and "vertere" – to turn, or "versus" (see verse), hence, "to turn against."
