lähteessä

Lähteessä is a Finnish word meaning “in the source” or “at the source.” It is the inessive form of the noun lähde, which can refer to a natural water source such as a spring, as well as to a beginning or origin of something, including information or ideas.

Grammatically, lähteessä is the singular inessive case form used to indicate location within or at a place referred to by lähde. The basic plural form is lähteissä, meaning “in the sources.” The word is common in naturalistic descriptions as well as in figurative uses related to origin or basis.

Usage notes: In literal, physical contexts, lähteessä often describes water sources, for example, Lähteessä virtaa kirkas vesi (“Clear water flows from the spring”). In figurative or informational contexts, the phrase can appear when referring to the information found in a source, for instance, Lähteessä mainittu tieto on virheellinen (The information mentioned in the source is incorrect). In academic writing, one typically discusses sources by title or author, but the expression lähteessä can still be used to indicate the location of material within a cited work or document.

Etymology and related forms: Lähde means “source” or “origin,” and lähteessä is its inessive form. Related terms include lähde, lähteet (plural), and and compounds such as lähdeluettelo (bibliography) or lähdeveden (water from a source) in context-specific usages.
