Indekseiksi

Indekseiksi is a Finnish translative plural form of the noun indeksi (index). It is used to express “as indices” or “into indices” when a group of terms, items, or features is designated, classified, or transformed into indices within a text, a dataset, or a reference system. For example, sentences such as “Termit määriteltiin indekseiksi” illustrate the use of the plural translative form to indicate that terms have been defined or designated as indices.

In Finnish grammar, the translative mood (ending in -ksi or -seksi in plural) marks a change of state, role, or function. Indekseiksi appears in contexts where a plurality of elements is being described as indices rather than as raw items. It is commonly found with verbs that express labeling, reclassification, or conversion, such as määriteltiin, jaettiin, tai muutettiin.

Usage and scope: The term is primarily a grammatical tool within Finnish and is most common in technical or analytical writing. It signals that a set of items is being treated or used in the capacity of indices, rather than as ordinary terms. It does not denote a separate technical concept beyond its role as a translative plural form of indeksi.

Etymology and related forms: The word indeksi comes from Latin index. Finnish uses the translative suffix -ksi (plural form often realized as -seiksi in indeksi-derived words) to indicate a state of becoming or designation, yielding indekseiksi for the plural.
