Which is the primary sense of the verb 'coordinate'?

• A. To make two or more things work well or efficiently together
• B. To harmonize
• C. To match
• D. To separate

Answer: (A)

Coordinate mainly means bringing different parts into a system where they can function together smoothly. It involves organizing and aligning actions, resources, or schedules so that two or more things work well or efficiently as a whole. For example, a project manager coordinates designers, developers, and testers to hit deadlines, showing how the focus is on harmony and synchronized effort rather than just appearance or separation. While harmonize is related, coordination emphasizes the process of arranging elements to operate in concert; matching relates to similarity or pairing, and separating is the opposite of bringing things together.
