refl

Refl is a compact form used in various technical contexts to denote reflection or related ideas. Because it is not standardized, its exact meaning depends on the field and the surrounding terminology.

In computing, refl commonly refers to reflection capabilities in programming languages. Reflection is the ability of a program to inspect and manipulate its own structure and behavior at runtime. With reflection, software can examine type information, enumerate object members, create instances dynamically, and invoke methods without static knowledge of their types. These features support flexible serialization, testing, and framework development, but they can incur performance overhead and raise security considerations if exposed to untrusted input or code.

In linguistics and language annotation, refl is often shorthand for reflexive or reflexivity. Reflexive forms and markers indicate that the subject and the object of a verb refer to the same entity. In annotation schemes, tags such as REFLEX or refl may be used to mark reflexive pronouns or reflexive verb forms within corpora or grammars, aiding cross-linguistic comparison and parsing.

In crystallography and diffraction studies, refl commonly stands for reflections observed in X-ray or electron diffraction experiments. Reflections are categorized by Miller indices and carry intensity information used to determine the arrangement of atoms in a crystal. Data files and analysis logs frequently reference reflections or groups of reflections, with careful treatment during indexing, scaling, and structure refinement.

Because refl has multiple legitimate meanings, readers should interpret it within the relevant disciplinary context. See also reflection, reflexive, and diffraction.
