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).
Pornography
The word "pornography" was coined from the ancient Greek words ("pórnē" "prostitute" and "porneía" "prostitution"), and ("gráphein" "to write or to record", derived meaning "illustration", as in "graph"), and the suffix -ία ("-ia", meaning "state of", "property of", or "place of"), thus meaning "a written description or illustration of prostitutes or prostitution". No date is known for the first use of the word in Greek; the earliest attested, most related word one could find in Greek, is , "pornográphos", i.e. "someone writing about harlots", in the "Deipnosophists" of Athenaeus. The Modern Greek word "pornographia" (πορνογραφία) is a reborrowing of the French "pornographie".
