The word "电话簿" (diànhuàbù), meaning "telephone directory," is formed through logical compounding in Chinese, where distinct meaningful characters combine to create a new, specific concept. It is constructed from "电" (diàn, electricity), "话" (huà, speech), and "簿" (bù, book or register). The first two characters, "电话," themselves a compound meaning "telephone" (literally "electric speech"), modify the third character "簿," indicating the type of book. Thus, the formation follows a modifier-head structure, where "电话" describes the purpose of the "簿," resulting in the clear and intuitive meaning of a "book for telephone numbers."
