Ironic refers to a situation, event, or statement that seems different or opposite to what one would expect. It often involves a contrast between what is expected or intended and what actually happens. In the case of "The Gift of the Magi" by O. Henry, the story is about a couple who make sacrifices to buy each other Christmas gifts, only to realize that their gifts are no longer useful. The irony lies in the unexpected outcome and the contrast between their intentions and the result.
