The term zig-zag is of uncertain origin. It seems to have first appeared in print in a Dutch publication in 1706; it appeared in English around 1728. It is probably a variation of the German word "zickzack." This word evidently referred to castle fortifications, which were often built in a zig-zag form; the word "zick-zack" was also used in English, along with "zic-zac," until "zig-zag" seemed to become the standard--- if such things really have standards.
