The term "above-cited" conveys that a particular source or reference has been previously mentioned and is being referred to again in a text. There are several synonyms that can be used in its place, such as "aforementioned," "previously stated," "earlier referenced," or simply "cited." Other possible alternatives include "referred to above," "mentioned previously," or "as previously noted." These synonyms can help to vary the language used in a text and avoid repetition. It is important to choose the appropriate synonym based on the context and tone of the writing, and clarity should always be the main priority when using any word to refer to a previously mentioned source or reference.
