The word "个个" (gègè) is formed through the **reduplication of the universal measure word "个."** This process transforms the single unit counter into a distributive pronoun meaning "each and every one" or "all." By repeating the character, the meaning shifts from denoting an individual item to emphasizing the totality of items within a group, distributively applying a quality or action to every single member without exception. It is a standard grammatical construction in Chinese where the reduplication of certain measure words creates an **adverbial or pronominal form** that expresses universality and collective individuality.
