In a manner showing that you feel insulted or offended.
Affronted + -ly (adverbial suffix). The adverb form allows 'affronted' to modify verbs, turning the adjective into a way of describing how an action is performed with wounded pride.
Adding '-ly' to adjectives is so common we barely notice it, but it's a clever linguistic system—you can describe someone speaking affrontedly without needing a whole new word!
