The meaning of COMBINATION is a result or product of combining; especially : an alliance of individuals, corporations, or states united to achieve a social, political, or economic end.

In mathematics, a combination is a selection of items from a set that has distinct members, such that the order of selection does not matter (unlike permutations).

So, in Mathematics we use more precise language: When the order doesn't matter, it is a Combination. When the order does matter it is a Permutation.
