The word 遥远 is formed through the combination of two individual characters, 遥 (yáo) and 远 (yuǎn), which both independently carry the core meaning of "distant" or "far". Their pairing is not grammatical but semantic, where the two near-synonyms are joined to reinforce and intensify the single, vivid concept of a vast, expansive distance, creating a more poetic and emphatic sense of "faraway" or "remote" than either character might convey alone.
