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).
Osprey
The origins of "osprey" are obscure; the word itself was first recorded around 1460, derived via the Anglo-French "ospriet" and the Medieval Latin "avis prede" "bird of prey," from the Latin "avis praedæ" though the Oxford English Dictionary notes a connection with the Latin "ossifraga" or "bone breaker" of Pliny the Elder. However, this term referred to the Lämmergeier.
