Essays / truth, hope, despair, faith, and hate - Definition essay [2]

Hi everybody. I need help writing a definition essay, and I have no clue how to. I've done lots of research but still I'm lost when it comes to writing this essay. The words my teacher gave me are truth, hope, despair, faith, and hate. She says I have to pick a lens on how I want to define it. Please, any ideas help.
