The word **干劲 (gànjìn)** is a modern Chinese compound formed by combining two characters: **干 (gàn)**, meaning "to do" or "to work," and **劲 (jìn)**, meaning "strength," "energy," or "vigor." Together, they create a metaphorical meaning where the "strength for work" translates idiomatically to "enthusiasm," "drive," or "motivational energy." It is a typical example of a coordinative compound where both elements contribute equally to an abstract, blended concept—neither merely modifies the other—resulting in a noun that encapsulates the dynamic spirit and zeal applied to a task or endeavor.
