The word "奈何" is formed by combining the characters 奈 and 何. 奈 originally derived from a character representing a fruit tree but later acquired the interrogative sense of "how" or "what to do". 何 is a pictophonetic character with the radical 人 indicating human-related meaning and the phonetic component 可 providing sound, meaning "what" or "how". When joined, these characters create a compound that conveys "how to deal with" or "what can be done", based on their shared interrogative functions.
