風立ちぬ (Kaze Tachinu) is a new movie from Hayao Miyazaki (The one who was involved with Princess Mononoke, Spirited Away, Howl's Moving Castle, My Neighbor Totoro, etc.).
Most translations translated the title as "The Wind Rises" or "Wind Rises". I know that:
風 means wind
立つ means stand, rise, go up
But what does "tachinu" mean? What conjugation is that?
Any help would be appreciated
