Here's a breakdown of what it *could* potentially mean:
* "Quel" is French for "what" or "which."
* "Dique" is a Spanish word for "dike," which is a structure built to hold back water.
Possible Interpretations:
* A question: "What dike?"
* A descriptor: "That dike" (referring to a specific dike).
* A phrase with a specific meaning in a particular context: If you heard this phrase in a specific situation, it might have a different meaning depending on the context.
If you can provide more context about where you heard or saw "quel dique," I might be able to help you understand its meaning.
