The word "更为" is formed by combining the character "更" (gèng), which means "more" or "further", with the classical Chinese particle "为" (wéi), which here serves to formalize and intensify the sense of comparison. This fusion creates a single, cohesive adverb that carries a stronger, more literary, or more emphatic tone than "更" alone, essentially heightening the degree of the adjective or verb it modifies.
