The phrase "as above" is commonly used to refer to something that has already been mentioned or explained. There are several synonyms that can be used in place of "as above" to avoid repetition in writing or speech. Some alternatives include "as previously stated," "as mentioned earlier," "as indicated before," or simply "as noted." Using these alternatives not only helps to keep language varied and interesting, but it also shows that the writer or speaker is paying attention to their audience by not assuming they remember all the details. It's always good practice to choose a synonym that best suits the context in which it will be used.
