Keitoista

Keitoista is a term used in Finnish language studies to describe a morphological form associated with the noun keitto (soup). It denotes origin from multiple soups and is treated as the elative plural in linguistic descriptions. The form appears primarily in grammars, dictionaries, and discussions of noun inflection rather than in everyday conversation.

Formation and usage: In standard Finnish, the elative plural is one of the plural inflections for nouns like keitto, and keitoista is cited as an example of how the suffix -ista/-istä attaches to the stem to express “from Xs.” The form is most commonly encountered in explanations of grammar rather than in ordinary speech, where speakers would typically use simpler expressions such as “from soup” or “from soups” in descriptive contexts.

Context and relevance: In linguistic education and descriptive grammars, keitoista may be used to illustrate stem changes, pluralization, and the interaction of case endings with noun classes. It helps learners understand how Finnish conveys origin or source with plural nouns and how such forms relate to other cases and numbers.
