Desensitize → It is formed from "de-" (meaning down or away) and "sensitize" (from Latin "sensibilis", meaning able to feel). The word describes the process of making someone or something less sensitive or responsive to stimuli, effectively taking away the ability to feel.
Think of 'taking away' ('de-') the ability to 'feel' ('sensitize') — that's why desensitize means to make less sensitive.
