When the parts of the whole work or fit together well, they are cohesive, like a cohesive family whose members pitch in with everything from making dinner to painting the house.

The adjective cohesive comes from the Latin word cohaerere, or “to cleave together.” Cohesive things stick together, so they are unified. A cohesive neighborhood's members get together to plan things like block parties, and they work together to solve problems. A cohesive fitness plan would include menus and exercise routines designed to lose weight, build muscle, and so on.
