Permutation and Combination...The Difference

Given a basic probability question, what key word(s) make clear that it is a permutation or combination problem? I do not have a specific question. Can someone provide me with a word problem for each case?

Knowing that order does not matter for combination versus a permutation where order does matter tells me nothing when reading the word problem.

Yes, it should be called a permutation lock but only math people would truly understand and appreciate its definition.
