The word "为何" is formed through the classical Chinese method of combining two independent, meaningful characters into a fixed compound. The character "为" (wéi), which carries a core sense of "being" or "doing", is paired with the interrogative character "何" (hé), meaning "what". Their fusion creates a conceptual unit that literally reads as "for what" or "being what", which directly and economically conveys the sense of "why". This formation reflects a traditional pattern of constructing abstract interrogatives by linking a functional character with a fundamental question word.
