Generate all possible unique groupings of the specified size from a given list of words, where the order of the words in each group doesn’t matter. For example, the words apple, banana, and cherry in groups of two would produce the pairs apple-banana, apple-cherry, and banana-cherry. The group banana-apple or any other reversed duplicates would not be generated since the order isn’t considered.
