Intervaly

Intervaly is a term used in several languages to denote the plural of interval, referring to multiple intervals in various disciplines. In English, the standard plural is intervals, but intervaly appears in contexts where Slavic or related languages are involved. The term typically signals a collection or set of separate intervals rather than a single continuous segment.

In mathematics, an interval is a connected subset of real numbers between two endpoints. Intervals can be open, closed, or half-open, such as (a, b), [a, b], or [a, b). They may also be unbounded, like (−∞, c) or (d, ∞), and can be finite or infinite. When speaking of intervaly, one would usually refer to a union or assortment of such intervals, or to a study of their properties, overlaps, and limits within a given context.

In statistics and data analysis, intervals often arise as confidence intervals, prediction intervals, or measurement ranges. If a writer uses intervaly, they may be describing several such intervals together—for example, multiple confidence intervals calculated for different parameters or samples.

In music and timekeeping, intervals describe pitch distances or temporal gaps between events. An intervaly in these fields would denote a set of such distances or gaps, rather than a single interval.

Etymologically, intervaly reflects the plural form used in some European languages for the English concept of an interval. In English-language texts, it is more common to use intervals. The usage and meaning of intervaly thus depend on linguistic context and disciplinary domain.
