cohering or tending to cohere; well-integrated; unified
of or pertaining to the molecular force within a body or substance acting to unite its parts
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.
