Permutation Words in awk

i have 13 different words. I need to get permutations like all combinations of this words:
word1 word2 word3 word4 word5 word6 word7 word8 word9 word10 word11 word12 word13
But the combinations only should be 12 words long.

Is there a fast efficient way to do this? Maybe with linux tool awk?

The term "all combinations" can mean different things to different people. Please show us what you would want as the output if you had three different words (word1, word2, and word3) but the combinations should only be two words long.
