In French, the word for ‘whatever’ is ‘quoi que ce soit’ or simply ‘n’importe quoi’ depending on the context.
When you want to express indifference or a sense of carefree disregard, you might use ‘n’importe quoi.’ For example, if someone asks if you care about a situation, you could reply, ‘N’importe quoi!’ meaning ‘I don’t care.’
On the other hand, if you’re referring to something in a more general sense, especially in a question or a more abstract way, you might say ‘quoi que ce soit.’ This translates to ‘anything’ or ‘whatever it may be,’ which can be useful in various conversations.
