Állandó

Állandó is a Hungarian word that functions primarily as an adjective meaning permanent, lasting, or enduring. It is used to describe something that does not change over time or that persists for a long period. In everyday language it appears in phrases such as állandó lakos (permanent resident), állandó munkahely (permanent job), and állandó hőmérséklet (constant temperature).

Etymology and form: the term is formed from the verb áll "to stand" together with the participial suffix -andó, which conveys an ongoing or enduring state. In modern Hungarian it operates as an attributive adjective and can also function in predicative position, for example, Ez állandó. (This is permanent/constant.)

Usage in different domains: in common speech, állandó describes enduring conditions, statuses, or characteristics. In science and mathematics it is used as a technical term for a quantity that does not vary, i.e., a constant. Expressions such as állandó érték (constant value) or állandó szám (constant number) reflect this sense. In physics and engineering the term can describe fixed parameters or properties that remain unchanged under specified conditions.

Grammatical notes: while primarily an adjective, állandó can appear in contexts where the concept of permanence is central, and in some texts it may be encountered as a noun referring to a constant, though this usage is less common in everyday language.

See also: the related idea of permanence or constancy appears in many compound phrases and disciplines, including geography (permanent resident), meteorology (constant temperature), and mathematics (constant values). Állandó remains a versatile term across both general and technical Hungarian.
