The word “equivalent” functions as a bridge connecting terms, concepts, or entities that share the same value or role, regardless of differences in language, culture, or context. It often appears when a writer wishes to clarify a term’s meaning through a familiar counterpart, such as equating a Greek word with its English analog ([1], [2], [3]) or aligning cultural markers between distinct communities ([4], [5], [6]). In both literary and scholarly works, it is employed to underscore similarities in function or character—whether in translating military ranks ([7]), establishing relationships in logical discourse ([8], [9], [10], [11]), or even in rendering idiomatic expressions understandable for a new audience ([12], [13], [14]). This versatile use emphasizes that despite the varied appearances or contexts, certain elements can be understood as fundamentally the same.
