Summary
Adhesion is fundamentally about the 'sticking' of different entities, whether they are physical surfaces (engineering), biological tissues (medicine), or political bodies (law). For example: 'The paint failed due to poor adhesion to the metal surface.'
- Adhesion is the physical attraction between different substances, such as glue sticking to wood or water sticking to glass.
- In medicine, it refers to scar tissue (adhesions) that causes internal organs to stick together, often after surgery.
- In legal and political contexts, adhesion means formally joining a treaty, agreement, or a specific cause or organization.
- It is a formal noun; the verb form is 'adhere'. It is often confused with 'cohesion', which is sticking to oneself.
