Anastrophe

Anastrophe (from the Greek: ἀναστροφή, anastrophē, "a turning back or about") is a figure of speech in which the normal word order of the subject, the verb, and the object is changed. For example, subject–verb–object ("I like potatoes") might be changed to object–subject–verb ("potatoes I like").

One of the most well-known characters who speaks in anastrophe is Yoda from the Star Wars films. When he wants to state that failure is the best teacher, he says “The greatest teacher, failure is.”
