Why does Yoda talk backwards?

In inventing languages for aliens in movies, writers often follow the language patterns in other Earth languages ( for example Klingon is in the word and case format of Swahili and Spock talks in Vulcan which is French written backwards). Even Jar Jar Binks is given an accent and speech pattern similar to that of the West Indies.

In Yoda's case, he is not talking backwards or in a foreign language. He is arranging the adjectives, nouns and verbs in the format of Latin. As an example, the Latin saying "Vir sapit qui pauca loquitur." is generally translated as "It is a wise man who speaks little." However a word for word translation comes across as a very Yoda like "A man of wisdom (is he) who little speaks" and Virgil's "Audentis fortuna iuvat" is generally translated as "Fortune favors the brave." but is really a Yodaesque "Boldness the fortunes favour."
