Rainy → It is formed from "rain" (from Old English *regn*, meaning water droplets falling from the sky) and "-y" (a suffix used to form adjectives indicating a characteristic). The word "rainy" describes a characteristic of having rain or being marked by rain.
Think of the Old English word for water droplets falling from the sky — that's what makes a day 'rainy'.
