klusterissa

Klusterissa is the inessive singular form of the Finnish noun klusteri, meaning “in the cluster.” The term is used to describe location or membership within a cluster in various scientific and everyday contexts. Grammatically, klusteri is a loanword from English cluster, with Finnish inflection forming forms such as klusterissa, klusteriin and klusterista to indicate different relations to the cluster.

In scientific Finnish, klusteri and its inflected forms appear in fields such as astronomy, data analysis and social sciences. In astronomy, writers talk about tähtiklusteri or galaktinen klusteri, referring to a group of stars or galaxies; a member object can be described as being in the cluster with klusterissa. In data science, clustering groups data points into sets, and a point’s status can be described as belonging to a particular klusteri, for example “pisteet ovat klusterissa 2.” The term thus functions both as a general descriptor of a grouped arrangement and as a phrase indicating position within that arrangement.

Semantically, klusterissa emphasizes membership or location within a defined cluster, where the exact composition depends on the criteria used to form the cluster (distance, density, similarity, etc.). Related terms include klusterointi (the process of forming clusters) and klusterin jäsen (a member of the cluster).
