  I would try:

words = ToString /@ {fall, winter, spring, summer};
Module[{test, w = words}, While[w != {},
    test = First[w]; w = Rest[w];
     Print[StringJoin[Reverse[Characters[test]]]]; ]]

where the Module[] protects global variables with names "test" and "w".

P.S.: again, spring is most amusing :-)
