Latin v - French g

Today I was really proud of my student Mirela Bertin Carnietto (she said it's okay to disclose her name here) when she exclaimed she had found a way to remember how to say snow and light in French (neige and léger). She said all you had to do is change Portuguese v for French g: neve - neige, leve - léger. I looked at her and announced: "You're totally right, I'd never thought about that". That thinking took me to Latin, which has nix, nivis for snow and levis, levis for light, which took me to Latin cavea, which became cage in French (and was taken by English with the same meaning). Voilà! I'm glad I'm instilling some linguistic thoughts in some of my students.
