muuttumattomat

Muuttumattomat is the plural form of the Finnish adjective muuttumaton, meaning "unchanging" or "immutable." As a noun phrase it is used to refer to things, properties, or concepts that do not change, remaining constant under given conditions.

The term is most commonly encountered in philosophical or literary contexts, where it can denote unchanging essences or forms, or the idea of permanence beyond fluctuation. In scientific and mathematical discussions, Finnish usually favors terms such as invariantti or invariant properties, while muuttumattomat is occasionally used to translate or paraphrase the English "immutable" or "invariant."

In computer science and programming, muuttumattomat can describe immutable data structures or objects—those whose state cannot be modified after creation. In Finnish technical writing one might encounter phrases like muuttumattomat oliot describing such objects.

Usage notes: Although the word accurately conveys non-changeability, its interpretation depends on context. When precision is required, it is better to use more established Finnish terms such as muuttumattomuus (immutability) or invariantti for mathematical contexts.
