"Fanny Adams" is a slang term used to describe something that is of no value or use. While this term may be commonly used in certain regions, it is important to use professional language in formal settings. Instead, words like "worthless", "useless", "meaningless", and "pointless" could be used as synonyms for "Fanny Adams". Other alternatives include "trivial", "insignificant", "unimportant", and "inconsequential". Using more appropriate language not only shows professionalism but also enhances effective communication. Therefore, it is crucial to consider the context and audience when choosing the right words to convey an idea.
