In Dutch, the verb koken means "to cook" or "to boil". In English, their is a distinction. Cooking implies a permanent change in the food. I can boil water, and when it cools it becomes cold water again. I can cook food, and when it cools it is still cooked food, not raw. If I heat pasta until it just boils, then turn off the heat, I have boiled pasta - but I have not cooked it.
