entrópiát

Entrópiát is the definite accusative singular form of the Hungarian noun entrópia, which corresponds to entropy in physics and information theory. The base word entrópia comes from the Greek entropia and entered Hungarian scientific vocabulary through Latin and German.

In Hungarian grammar, entrópiát is used when entropy functions as the direct object of a verb and the object is definite. The definite object is marked by the suffix -t, so phrases such as az entrópiát mérik (they measure the entropy) or növelik az entrópiát (they increase the entropy) illustrate its use. The form reflects the broader rule that definite objects receive the corresponding suffix to indicate definiteness.

In scientific contexts, entropy is a fundamental concept describing disorder or uncertainty. In thermodynamics, it gauges the number of possible microstates of a system and tends to increase in irreversible processes. In information theory, entropy measures the average information content or surprise of a source’s outputs. While the underlying idea is consistent—entropy as a measure of disorder or information content—the interpretation and units differ across disciplines.

Linguistically, entrópiát exemplifies how Hungarian marks definiteness on the direct object, independent of whether the term is used in everyday speech or specialized scientific writing. The related noun entrópia serves as the general term, with entrópiát functioning as its definite accusative form when required by sentence structure. See also: Entropy, Entrópia.
