coeziunea

Coeziunea is a general term used across disciplines to denote the property of being held together or the forces and connections that bind a system into a unified whole. In Romanian usage the term covers physical, social, linguistic, and structural contexts, and is derived from Latin cohaerere through the French cohésion.

In the natural sciences, cohesion refers to the attraction between like molecules within a substance. This intermolecular bonding gives rise to phenomena such as surface tension in liquids and the internal strength of materials. Cohesion contrasts with adhesion, the attraction between unlike substances. The concept also appears in soils and materials science as cohesive strength, describing the internal forces that resist deformation or rupture, particularly in clay-rich soils.

In the social sciences, social or communal cohesion denotes the degree to which members of a society or group feel connected and committed to common norms and goals. It depends on factors such as trust, social capital, equality, and the effectiveness of institutions, and it is linked to outcomes like civic participation, social resilience, and stability.

In linguistics, textual cohesion refers to the set of linguistic links that connect parts of a text, including reference, repetition, substitutions, and conjunctions, which support coherence and readability.

Overall, coeziunea describes the cohesive force or property that maintains unity within a system, whether physical, social, linguistic, or structural.
