muundumine

Muundumine is an Estonian noun meaning the act or process of transforming or converting something from one form, state, or condition to another. It is used across disciplines to describe deliberate, systematic changes and may refer to physical, conceptual, or formal transformations. The related verb is muunduda, and muundumine is commonly encountered in mathematical, scientific, and linguistic contexts.

In mathematics, muundumine describes a function or rule that assigns to each element of a domain a single element of a codomain, i.e., a mapping. When the transformation preserves a structure, it is often called a transformation. Examples include linear transformations of vector spaces, rotations, translations, and coordinate changes.

In science and engineering, muundumine covers energy, matter, or signal changes. Energy muundumine refers to conversion between forms, such as potential to kinetic energy. In chemistry, chemical reactions are described as muundumid of substances, while in signal processing, muundumine can refer to mathematical transformations of data, such as Fourier or wavelet transforms.

In linguistics and computer science, muundumine denotes form changes, such as morphological muundumine (derivation or inflection) or data transformations in programs and databases. The concept is often linked to invertibility: a reversible muundumine corresponds to a bijection, though many practical transformations are not strictly reversible.
