Input (English): Serein (/sɪˈriːn/; (səʁɛ̃) in French) refers to rain falling from a cloudless sky. This sort of rain is said to take on the form of a fine, light drizzle, typically after dusk. The name derives from French serein, meaning ``serene'', or ``clear'' (as in unclouded). An alternative etymology is from Old French serain, evening.
Output (English): can it rain if there are no clouds?
