When someone is affronted by something, it means they feel offended or insulted by it. However, there are many different ways to express this type of negative reaction. For example, instead of saying "I was affronted by your behavior," you could say "I was offended," "I was insulted," "I was hurt," "I was angry," or "I was upset." Other synonyms for "be affronted by" include "be outraged," "be affected," "be bothered," "be vexed," and "be displeased." No matter which word you choose, it's important to communicate your feelings clearly and directly to the person who has caused offense.
