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).
Creativity
The lexeme in the English word "creativity" comes from the Latin term "creō" "to create, make": its derivational suffixes also come from Latin. The word "create" appeared in English as early as the 14th century, notably in Chaucer, to indicate divine creation (in The Parson's Tale). However, its modern meaning as an act of human creation did not emerge until after the Enlightenment.
