Yoda speaks in an archaic, formal mode of English, that originated in Anglo-Saxon, where the verb is placed at (or very near) the end of the clause or sentence.

The way to imagine the construction of one of these sentences is as a stage. First you set the location (around), then the actors (the survivors), then lights, camera (a perimeter), then action (create).

Use this rule and you, too, can always create an authentic Yoda sentence (and/or write Ye Olde Englisc prose (VYMM)).
