äideistä

äideistä is a Finnish noun form. It is the elative plural of äiti (mother), and it translates roughly as “from the mothers” or “out of the mothers.” This form is used to indicate origin, source, or basis when the source is mothers or a maternal group, for example data, statements, or traits associated with mothers.

Formation and grammar: The base word is äiti. In the elative plural, the stem changes to äide- and the suffix -stä or -stä is added, giving äideistä. The singular elative is äidistä, and the broader inflection of äiti includes nominative äidit (mothers) and genitive plural äitien (of mothers). The word illustrates how Finnish employs stem changes in different cases, not only fixed suffixes.

Usage: äideistä is common in contexts such as research or ethnographic descriptions, where information is collected from mothers. It also appears in discussions of maternal influence or inheritance, for example: “Tutkimus perustui äideistä kerättyihin tietoihin” (The study was based on information collected from mothers) or “äideistä periytyviä ominaisuuksia” (traits inherited from mothers). The elative plural form helps clarify the source as maternal rather than general or paternal.

Notes: As with other Finnish case forms, the exact meaning of äideistä is determined by context and surrounding verbs or nouns. It is primarily used in formal or descriptive language, including scientific writing and genealogical or sociolinguistic discussions.
