Downfallen → It is formed from "down" (from Old English "dūn", meaning from a higher place to a lower place) and "fallen" (from Old English "feallan", meaning to fall). The word "downfallen" describes something that has fallen down or is in a state of decline.
Think of something that has moved from a higher place to a lower place ('down') and has 'fallen' — this helps you remember that 'downfallen' means something that has fallen down.
