Erinevus

Erinevus is an Estonian noun meaning difference, distinction, or disparity. It denotes the quality that makes two or more things not the same and is used to describe contrasts between objects, concepts, measurements, or outcomes in everyday language and in more formal or technical contexts.

In mathematics and science, erinevus refers to the result of comparing values or to the broader concept of dissimilarity between quantities. It is used to discuss the difference between data sets, between observed and predicted values, or between competing measurements and theories.

In linguistics, philosophy, and related fields, erinevus is used to articulate contrasts between meanings, categories, or conceptual frameworks. The term helps to express how one idea or object differs from another in properties, attributes, or implications.

Origin and form: Erinevus is formed from the adjective erinev (different) with the noun-forming suffix -vus. It is a standard term across Estonian writing and speech, used across education, media, science, and everyday discourse to convey the notion of non-equivalence or distinction.
