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).
Pasha
According to "Etymonline", pasha is derived from the earlier "basha", itself from Turkish "baş/bash" (head, chief), itself from Old Persian "pati"- "master", (from Proto-Indo-European *"poti") and the root of the Persian word shah. According to the "Oxford Online Dictionary", the word has its origins in the mid-17th century, and was formed as a result of the combination of the Pahlavi words "pati-" "lord", and shah. According to Josef W. Meri and Jere L. Bacharach, the word is "more than likely derived from the Persian Padishah". The same view is held by Nicholas Ostler, who mentions that the word was formed as a shortening of the Persian word Padishah. According to etymologist Sevan Nişanyan, the word is derived from Turkish "beşe" ('boy, prince'), which is cognate with Persian "baççe" (). Old Turkish had no fixed distinction between /b/ and /p/, and the word was spelled "başa" still in the 15th century.
