Lahendusest

Lahendusest is an Estonian inflected form of the noun lahendus (meaning "solution") that uses the case ending -est. As a case form, it commonly functions as the elative case, which indicates movement out of something, origin, separation, cause, or source. In syntax it can also serve the semantic role of "about" when used with verbs that govern the elative (for example, rääkima, arutama).

Morphology and formation: lahendusest is formed by attaching the elative ending -est to the noun stem lahendus. It contrasts with related forms such as lahenduse (genitive) and lahendust (partitive).

Typical uses and translations: depending on context, lahendusest can be translated into English as "from the solution", "out of the solution", "because of the solution", or "about the solution". For example, Arutasime lahendusest translates as "We discussed the solution" (literally "we talked from/about the solution"), while Tekkis probleem lahendusest can mean "A problem arose from the solution."

Syntactic notes: many Estonian verbs and prepositions require or conventionally take the elative to indicate topic or source (e.g., rääkima millest, kirjutama millest). Usage and nuance depend on verb valency and context; in some cases alternative cases or constructions (such as the partitive or prepositional phrases) may be preferred for emphasis or clarity.

Pronunciation: pronounced roughly [ˈlɑhendusest], with stress on the first syllable.
