The Chinese word **入手** is a compound verb formed by combining two characters: **入** (rù), meaning "to enter" or "to start," and **手** (shǒu), meaning "hand." Together, they create a metaphorical meaning of "to start with" or "to begin doing," implying the initial point of action where one "lays hands on" a task or problem. This formation follows a common pattern in Chinese where concrete body parts are used in verbs to express abstract actions, with **手** often relating to action or method, and **入** indicating the commencement or entry into that action. Thus, **入手** semantically shifts from the literal "enter the hand" to the idiomatic sense of "to begin," "to set about," or "to start from a particular point."
