ühildu

Ühildu is a term used in Estonian-language sources to describe the condition or state in which two or more entities can work together without conflict. It denotes compatibility and mutual interoperability between systems, components, data formats, or standards. The concept is widely used in information technology, electronics, data exchange, and organizational processes where different parts must function in harmony. An entity is ühilduv with another if they can operate together, exchange data, or cooperate without requiring modification.

Etymology and forms: The word is derived from the Estonian verb ühilduma (to be compatible or to harmonize). Related forms include ühilduvus (noun: compatibility) and ühilduv (adjective: compatible). In technical writing, ühilduvus is commonly used to discuss the level of compatibility between standards or interfaces.

Applications: In software engineering, ühilduvus describes API compatibility, file-format interoperability, and version compatibility. In hardware, it covers plug-and-play interoperability and standard conformance. In policy and organizational contexts, ühilduvus refers to alignment of procedures, security requirements, or regulatory standards across departments or partner organizations.

Limitations: Real-world compatibility can be contingent on versioning, configuration, and extended support. Two systems marketed as ühilduvad may still require adapters or mappings. See also: interoperability, compatibility.
