Common Pitfalls
Translation Traps (for Russian speakers)
- Не путать с 'декор' или 'декорировать' (украшать). Корень связан с лат. 'cortex' (кора), что ближе к слову 'кора'. Прямого однокоренного частого глагола в русском нет, перевод зависит от контекста: 'очищать от коры/скорлупы', 'удалять корковое вещество'.
Common Mistakes
- Using it intransitively (e.g., 'The bark decorticates' is incorrect).
- Confusing spelling with 'decorate'.
- Assuming it is a common synonym for 'peel' in everyday contexts.
