võrdeline

Võrdeline is an Estonian adjective meaning equal, equivalent, or proportional. It describes relations that are balanced, comparable, or related by a constant ratio.

Etymology: the word is derived from võrdus, meaning equality, with the common Estonian adjectival suffix -line.

Usage: In mathematics and science, võrdeline describes a proportional relationship between quantities; two quantities x and y are võrdelised if there exists a constant k such that x = k · y. In everyday language, the term can indicate that two items, values, or performances are on a comparable level or can be judged as similar in value or merit. Võrdeline thus conveys not only strict equality but also a sense of comparability or proportionality.

Relation to related terms: Võrdne means strictly equal, while võrdlus refers to the act or process of comparison. Proportion and proportional relationships are commonly discussed using terms like proportsioon in Estonian. As an adjective, võrdeline inflects like other Estonian adjectives, changing form according to number and case.
