Usually I tease you, gentle reader, with the ellipsis in a post title: “wait till you read the rest!” I implicitly promise.
This time the three dots are all I have; they end what I wrote down on a back page of my gradebook. The rest of the sentence was, presumably, okay, so I felt no need to preserve it for the ages.
The word choice in question is certainly let’s-say unorthodox: on its face, the phrase invites us to picture two adults whose bodies have been cleft in twain—producing four half-parents. Or perhaps the individuals are only partly split, like strands of hair with split ends. This is a funny picture, a moment of laughter the reader does want to preserve for the ages. A cartoonist could draw it.
But any reader, including this willfully obtuse professor (“It’s my job to misunderstand you if I can!”), knows exactly what my student meant: while she was growing up, her parents did not cohabitate. Part of the time they may have been only separated; in all probability they eventually divorced. If when they called it quits one even left town—and if they passed the child back and forth but never themselves sat down together, talked in a friendly way, got together with their offspring for a holiday or snack or college visit—then they completely split up. My student could have referred to this as a “split household,” or could have said “as a kid growing up with parents who had split up…,” both more orthodox ways of saying that.
(I could quibble with the “growing up with,” suggesting that it might be taken to mean the parents were growing up along with the kid, but I don’t choose to quibble with it. The rest of the words are more worthy of remark—I want to focus on the main feature.)
“Split parents” is so efficient: at once communicative not only of their physical and marital situation but also of a certain forlornness, wrongness, that the child must have felt. It is also to-the-point, concise. From the writer’s point of view it keeps the emphasis of the essay where it belongs, too: on the “kid.” Trying to be more factually precise or verbally conventional would have taken more time, more space, and more care than the bald fact merited; she was writing about herself, not about them.
I don’t think my student spent much time (if any) on the phrasing of her idea; I think she put it down straight from her head. But I think she said what she meant.
So I think this “error” must be let stand, especially in a sentence that also refers to a “kid”: that is, in a sentence that is generally informal in tone and diction.
Sometimes you have to let them be poets, even if that isn’t their intention. Sometimes their “error” invites you to take a fresh look at the language, and at the reality they are offering to share. Sometimes you teach, and sometimes you learn.
