“James while John had had had had had had had had had had had a better effect on the teacher” як це не дивно є цілком валідним реченням. Спробуємо його розібрати:
- James while John – якось коли Джон
- had had – використовував
- had – слово had
- had had – а Джеймс використовував
- had had – слова had had
- had had – ці слова (had had)
- had had – справили
- a better effect on the teacher – краще враження на вчителя.
