Etymology

Origin of adherence

< Medieval Latin adhērentia. See adhere, -ence

Explanation

Adherence means "sticking to" or "being faithful to," such as your adherence to your diet even when chocolate cake is around, or students' adherence to school rules — they do not use cell phones or music players in class. The noun adherence is related to the verb adhere, meaning “to stick.” If something adheres, it sticks it to something, like a bumper stick that adheres to a car or a person who adheres to a plan, not changing it along the way. Adherence describes this willingness to stick or be faithful, like adherence to child labor laws that means young workers cannot work past a certain time on school nights.
