intervallumát

Intervallumát is the Hungarian accusative form of the noun intervallum, which itself is a loanword from Latin intervallum meaning “interval.” In Hungarian, the suffix –t marks the direct object, so intervallumát translates literally to “its interval” or “the interval of.” The word is used across several domains where a bounded range, period, or space is referred to.

In mathematics an interval denotes a set of numbers that contains all real numbers between any two of its elements. Intervallumát may appear in discussions of a function’s domain, the time a process runs, or the spatial extent of a distribution. For example, a function f may be defined on the interval 1 ≤ x ≤ 5, and one would speak of the intervallumát [1, 5] to denote its limits. In set theory, a closed interval [a, b] is often compared to an open interval (a, b), and the intervallumát helps specify open versus closed boundaries.

Outside mathematics, intervallumát is used in other scientific and technical contexts such as acoustics, where the frequency range of a sound is called the intervallumát, or in statistics, where the confidence interval of a parameter is a key measure. In music theory, one may speak of the intervallumát between two notes, indicating the distance measured in semitones.

The term reflects Hungarian’s flexible use of agglutinative morphology. While intervallum itself is a borrowed term, its adaptation to Hungarian grammar—adding the accusative vowel –t—shows how loanwords are fully integrated. The combination intervallumát is thus a common phrase in written and spoken Hungarian when a specific interval is referenced as a direct object.
