What dws mean is:
  1. create an index array containing all valid index. For example, if you have a list of 5 words, then this index array world be (0,1,2,3,4).
  2. Shuffle this inddex array randomly, so it becomes something like (3,0,4,2,1). (I guess, the difficulty to you would be how to shuffle this array ;-)
  3. Now pick the words. For example, continue from step 2, say you want pick 2 words. As the first two elements of the shuffled index array is 3 and 0, so you just pick the words at index 3 and 0 of your word list.
