Aðgreina

Aðgreina is an Icelandic verb meaning to differentiate, distinguish, or separate. It denotes the act of making distinctions between items, features, or groups, or of separating something into components. In scientific and analytical contexts it refers to identifying differences and isolating elements for study. In linguistics and philosophy it can describe distinguishing categories or features. In everyday language it can also indicate the process of sorting or classifying things.

Noun form aðgreining means differentiation or discrimination, depending on context. Related nouns include greining (analysis, diagnosis) and greiningarferli (the process of analysis). The verb is formed with the infinitive marker að plus the verb greina, whose core meaning is to analyze or discern.

The concept covers a broad range of activities from simple distinction to systematic separation of mixtures, data, or concepts. It is used in academic writing to describe methodological steps as well as in practical contexts where categories or components must be separated or identified. In social and ethical discussions, aðgreining can refer to discrimination in the sense of treating people differently, which may carry a pejorative connotation depending on context. Overall, the term encompasses both neutral technical uses and potential normative implications depending on how it is applied.
