Stacked; verb, past tense; a number of things arranged in a stack or stacks. (definition from the Oxford Dictionary)
What is the difference between stacked and piled, you may wonder? According to my research, a stack is neat and orderly and a pile is messy. You might see stacks of pancakes, papers, rocks, books, or even stacked heels today. Let your imagination run wild and take a photo of any stacked item you find. Have fun!
