“A few days after the fireworks, I gave them a lesson on category nouns versus exact nouns. I hadn’t heard of this distinction prior to opening the textbook. It transpired that a category noun was something like “vegetables,” whereas exact nouns were “beetroot,” “carrots,” “broccoli.” It was better to use exact nouns because this made your writing more precise and interesting. The chapter gave a short explanation followed by an exercise: an A4 page divided into columns. On the left were various category nouns. On the right, you had to fill in at least three corresponding exact nouns. I told the kids they could use their Cantonese-to-English dictionaries. Cynthia Mak asked what to say for “people.” Did it mean “sister,” “brother,” “father,” or “teacher,” “doctor,” “artist,” or— “They’re all okay,” I said. “But if I put ‘sister,’ ‘father,’ ‘brother’ in ‘people,’ then what about here?” She pointed to the box marked “family.” “Okay, don’t do those. Do ‘teacher’ or something.” “But what about here?”—signaling the “professions” row. “Okay, something else for ‘people.’” “Happy people, sad people?” “‘Happy people’ isn’t an exact noun—it’s an adjective plus a category noun.” “So what should I write?” We looked at each other. It was indeed a challenge to describe people in a way not immediately related to how they earned money or their position in the family unit. I said: “How about ‘friend,’ ‘boyfriend,’ ‘colleague’?” “I don’t want to write ‘boyfriend.’” I couldn’t blame her for questioning the exercise. “Friend,” “enemy,” and “colleague” didn’t seem like ways of narrowing down “people” in the way “apple” did for “fruit.” An apple would still be a fruit if it didn’t have any others in its vicinity, but you couldn’t be someone’s nemesis without their hanging around to complete the definition. The same issue cropped up with my earlier suggestions. “Family” was relational, and “profession” was created and given meaning by external structures. Admittedly “adult,” “child,” and “teenager” could stand on their own. But I still found it depressing that the way we specified ourselves—the way we made ourselves precise and interesting—was by pinpointing our developmental stage and likely distance from mortality. Fruit didn’t have that problem.”
