Something described as cohesive sticks together and forms something closely united. The word is usually used with abstract terms in phrases like “a cohesive social unit” or “a cohesive look/aesthetic.” Cohesive can also be used to describe something, such as the design of a room or the plot of a movie, that is coherent—in other words, logically or consistently ordered.
The couple chose their wedding colors and designs carefully to make sure everything had a cohesive look.
The customer service department is a small but cohesive team.
