essapäätteineen

essapäätteineen is a Finnish term that translates literally to "with its end on the 's'" or "with an 's' ending." It is a grammatical concept used to describe certain word forms in the Finnish language. Specifically, it refers to nouns that have a genitive singular form ending in -s.

Finnish nouns have various case endings, and the genitive case is used to indicate possession or a similar relationship, akin to the English possessive 's. While many genitive singular forms end in other suffixes, a particular group of nouns historically or currently takes a genitive singular ending of -s. These are often referred to as "s-stem" nouns in linguistic analysis, though the term essapäätteineen focuses on the observable ending rather than the underlying stem classification.

Examples of words that exhibit this feature include "mies" (man), whose genitive singular is "miehen" (of the man) – this does not end in -s. However, some older or less common declensions might show this. A more common way to understand the concept is through derived forms. For instance, some adverbs or other word types can be formed from nouns, and these derived forms might take an -s ending in certain grammatical contexts, hence "essapäätteineen" referring to the presence of this specific ending. The concept is relevant for understanding the nuances of Finnish morphology and word formation.
