An example of how to use denigrate in a sentence Examples from video: 1) I'm into this fashion thing and I'm like doing shows and I'm like putting models on the stage and it's like I'm really on top of my game and it's just like someone tried to denigrate me. It's like I'm on top of everything like why would you try to put me down? Like why would you do such a thing?
