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).
Prose Edda
Another connection was made with the word "óðr", which means "poetry or inspiration" in Old Norse. According to Faulkes, though such a connection is plausible semantically, it is unlikely that "Edda" could have been coined in the 13th century on the basis of "óðr", because such a development "would have had to have taken place gradually", and "Edda" in the sense of "poetics" is not likely to have existed in the preliterary period.
