Here are some examples of how it's used:
* La couronne royale (The royal crown)
* Une couronne de fleurs (A crown of flowers)
* Elle porte une couronne de lauriers (She wears a crown of laurels)
It's important to note that "couronne" can also refer to other things besides a literal crown, such as:
* Couronne de dents (A crown of teeth)
* Couronne de bois (A crown of wood)
However, in the context of royalty, "couronne" is the most common translation for "crown."
