To make (something) less severe, harmful, or painful
I encountered this word from our reading experts, “Brooklyn was Mine” by Jennifer Egan. This word was used when Lucy mentioned in her letter where she often get a sore feet from her job. She solved her problem where she used rubber-sole shoes to lessen the pain from her feet. This word, “Mitigate” sounds like it is used in medical terms. Because of the “Miti” close to the word, “Mini” indicating making the pain “smaller” and the rest of the word, “-gate” converts to converting into something. Which in this case it converts pain less.
