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).
Fraujaz
The term's etymology is ultimately from a PIE "*pro-w-(y)o-s", containing "*pro-" "in front" (c.f. "first", "Fürst" and Sanskrit "purohita" "high priest", lit. "placed foremost or in front"). Variants indicate "n"-stems "*fraujan-", "*frōwōn-". The feminine *"frawjōn" "lady, "domina"" in Old English is attested only in a single isolated occurrence as "frēo" "woman" in the translation of the fragmentary Old Saxon "Genesis" poem, in the alliterating phrase "frēo fægroste" "fairest of women". The stem was confused from early times with "*frīj-", which has variants "frēo-, frīo-, frēa-" (a contraction of "*īj-" and a following back vowel) beside a less frequent "frīg-" (/fri:j-/), by development of a glide between "ī" and a following front vowel. The two forms would originally have figured in complementary distribution within the same paradigm (e.g. masculine nominative singular "frēo", masculine genitive singular "frīges"), but in attested Old English analogical forms are already present and the distribution is no longer complementary
