Erottamis

Erottamis is a Finnish noun form derived from the verb erottaa, meaning to separate or distinguish. In standard modern Finnish, the common noun for the act is erottaminen; erottamis is a relatively uncommon or older form, typically found in fixed expressions or as a stem in compounds. The sense centers on separation, differentiation, or selection, with nuance shaped by context.

The term covers a broad range of uses. In science and engineering, erottamista refers to processes that separate a mixture into its components, such as distillation, filtration, crystallization, centrifugation, and chromatography. In statistics and signal processing, erottaminen can describe the separation of signals or sources, often referred to as source separation or component extraction.

In linguistics and education, erottaminen is used for distinguishing features, sounds, or categories—such as phoneme erottaminen (distinguishing phonemes) or the differentiation of linguistic elements in analysis and teaching. In social or organizational contexts, erottaminen can denote separation or exclusion of individuals or groups, and in workplace language it may appear in the sense of dismissal or removal from a position, though more common terms include erottaminen or irtisanominen depending on jurisdiction and register.

Related terms include erottelu (distinction or segregation) and erottamistekniikka (techniques of separation). The form erottamis is generally considered a variant or historical form, with erottaminen preferred in contemporary Finnish.
