plural() should accept a single word. To handle list of words, call
map(plural, words)

Use functools.wraps() to preserve the function info for introspection:
import functools
def prints_result(function):
@functools.wraps(function)
def wrapper(*args, **kwargs):
result = function(*args, **kwargs)
print(result)
return result #XXX return
return wrapper
@prints_result
def hello(...):
pass
