Exploring the Multiple Meanings of “Adherence”
1. Following a Rule, Plan, or Standard
- Meaning: The act of carefully and continuously following a rule, plan, or standard.
- Explanation: This is the most common sense. It suggests steady, ongoing practice, not a single act. It is the sense of the verb adhere that means to bind oneself to observance.
- Example: The school requires strict adherence to its safety rules.
2. Loyalty to a Belief, Cause, or Group
- Meaning: Steady attachment to a person, cause, belief, or party.
- Explanation: This is the older sense. Etymonline traces it to the mid-15th century. It describes support that lasts over time, not a passing interest.
- Example: Her adherence to the party survived years of disagreements.
3. Sticking to a Treatment or Health Plan
- Meaning: How closely a person follows a prescribed treatment, such as taking medicine as directed.
- Explanation: This is a specialized use in health writing. It is often measured, as in “poor adherence” or “medication adherence”. Some writers prefer it to compliance because compliance can sound like blind obedience.
- Example: Doctors check patients’ adherence to their medication schedules.
4. Physically Sticking to Something
- Meaning: The state of sticking to a surface.
- Explanation: This sense is rare and mostly technical. Etymonline notes that adhesion is the usual word for the physical meaning, and Samuel Johnson observed that by the 18th century adhesion was used for material things and adherence for ideas.
- Example: Good adherence of the paint to the metal depends on a clean surface.

IPA: US /əbˈzɜːrvəns/ · UK /əbˈzɜːvəns/
