coordinate
To organize people or parts so they work together smoothly.
To coordinate means to organize different parts or people so they work together smoothly. When you coordinate a group project, you make sure everyone knows their job and when to do it so all the pieces come together at the right time. A teacher might coordinate a field trip by arranging the bus, the permission slips, the chaperones, and the schedule so everything happens in the right order.
The word can also mean making separate things fit together like puzzle pieces. A soccer team coordinates their movements on the field, with defenders, midfielders, and forwards working in harmony. Your brain coordinates your muscles when you ride a bike, making sure your legs pedal while your hands steer and your body balances, all at the same moment.
Coordinates (with an s) are also numbers that show an exact location on a map or grid. Sailors use coordinates to navigate the ocean, and game players use coordinates to mark treasure locations. When you plot points on a graph in math class, you're using coordinates like (3,5) to show precisely where something belongs.
Someone who coordinates is called a coordinator. Event coordinators organize weddings or conferences, making sure the food, music, decorations, and timing all work together to create one successful event.
