The word 业务 is formed by combining two conceptual building blocks: 业 (yè), which fundamentally represents one's profession, trade, or line of work, and 务 (wù), which denotes a task, duty, or affair. Their fusion creates a new, synthesized concept where the whole meaning transcends a simple sum of its parts. It conceptually merges the sphere of one's professional domain (业) with the active, practical matters and transactions conducted within it (务), resulting in the integrated idea of "business operations" or "professional services".
