"A strong wind blows."
I like the way she says "fuki". It's like she's gently spitting in my ear
The only thing that has come to bother me in these courses is the fact that the course introduces kanji that are then missing from the lesson onwards. Why doesn't this question use "風" when we already learned this kanji? It is weird.
「が」 is the subject marker particle in Japanese. It shows what is doing the action of the sentence (the action being blow, the wind doing the blowing).
