The word **电锯 (diànjù)** is a straightforward compound noun formed by combining the character **电 (diàn)**, meaning "electricity" or "electric," with the character **锯 (jù)**, meaning "saw." It follows the common Chinese word-formation pattern of a **modifier (electric) + core noun (saw)**, resulting in the meaning "electric saw" or, more specifically, "chainsaw." This structure directly and logically describes the tool's primary characteristic—its power source—in relation to its function, making it an intuitive and efficient term.
