Sure. Here is a longer answer to your question, without repeating myself:
The 6-letter Dutch word that means “of nature” is naturel. It is an adjective that describes something that is natural, genuine, or unprocessed. It can be used to describe food, cosmetics, or even people.
For example, you might say that a piece of fruit is naturel if it is eaten without any added sugar or other processing. You might also say that a person is naturel if they are honest and sincere, and do not try to pretend to be someone they are not.
Here is an example of how the word naturel might be used in a sentence:
Ik geef de voorkeur aan naturele producten, zonder kunstmatige toevoegingen.
(I prefer natural products, without artificial additives.)
I hope this is more helpful!
