#accession

• Accession — The act of adhering and its result; a formal, legal, and institutional process through which a state, entity, or individual becomes an integral part of a pre-existing political, economic, or social structure. In the contemporary history of Romania, the term refers structurally and symbolically to the process of full integration into the European Union and the North Atlantic Alliance.
• Adhesion — A molecular attraction phenomenon manifested at the contact surface between two different bodies, causing them to stick or join closely; in a social, political, and legal sense, it represents the formal act or public expression of attachment, approval, and joining of a person or group into an organization, party, or collective treaty. This structural term defines both the physical cohesion of materials and the ideological conformity of an individual.
• Adjunction — Union, joining, or structural addition of a secondary element to a main body or system; in civil law, it represents a form of property accession whereby two goods belonging to different owners are materially united into a single whole without losing their initial identity, such that their separation would become prejudicial. In logic and programming, it describes the operation of directly connecting variables or arguments within a linear structure.
• Adjunction — An obsolete and purely etymological form of the term 'adjuncție' (adjunction) or 'adjudecare' (in certain old contexts), used historically in academic or legal language to describe the act of formally adding or annexing a territory, a right, or an asset to a primary property. In classical civil law, it denoted a method of acquiring property by joining two movable goods belonging to different owners.
