Ilunga (Bantu): A person who is willing to forgive abuse the first time; tolerate it the second time, but never a third time. Apparently, in 2004, this word won the award as the world’s most difficult to translate. Although at first, I thought it did have a clear phrase equivalent in English: It’s the “three strikes and you’re out” policy. But ilunga conveys a subtler concept, because the feelings are different with each “strike.” The word elegantly conveys the progression toward intolerance, and the different shades of emotion that we feel at each stop along the way. Ilunga captures what I’ve described as the shade of gray complexity in marriages—Not abusive marriages, but marriages that involve infidelity, for example. We’ve got tolerance, within reason, and we’ve got gradations of tolerance, and for different reasons. And then, we have our limit. The English language to describe this state of limits and tolerance flattens out the complexity into black and white, or binary code. You put up with it, or you don’t. You “stick it out,” or not. Ilunga restores the gray scale, where many of us at least occasionally find ourselves in relationships, trying to love imperfect people who’ve failed us and whom we ourselves have failed.
