Addressings, a noun that refers to the manner or style of addressing someone or something, can have multiple antonyms depending on the context. In terms of formal language, the antonyms of addressings could be, for example, informality or lack of refinement. However, in the realm of interpersonal communication, addressings could be the antithesis of disrespect, dishonor, or disregard. To use the word "antonyms" for addressings in this context is a bit of a stretch. Rather than finding exact antonyms, using words that describe behaviors showing a lack of respect or consideration for others would be more accurate.
