UNCOVERING TRUTH (abstract): 'The investigation decorticated the layers of corruption.'

Watch out

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.
