päevavalgusest

Päevavalgusest is an Estonian word formed as the elative singular of the compound noun päevavalgus, which literally means "daylight" (päev "day" + valgus "light"). As an elative form, päevavalgusest conveys motion or origin "out of" or "from" daylight, and is used in both concrete and figurative contexts.

Grammatically, päevavalgusest illustrates regular Estonian case morphology: the base noun päevavalgus (nominative) yields related forms such as päevavalgust (partitive), päevavalguses (inessive, "in the daylight"), päevavalgusse (illative, "into the daylight") and päevavalgusest (elative, "from the daylight"). The elative case often marks movement from an interior or source, temporal points of origin, or cause.

In usage, päevavalgusest appears in literal descriptions (for example, indicating that someone or something moves out of open light into shade) and in idiomatic expressions relating to exposure, discovery or emergence (for instance, describing information that has become known "from the light of day"). It can also appear in literary and journalistic language to set contrasts between visibility and concealment.

Pronunciation is close to "päeva-valgusest" (approximate romanization: PAE-va VAL-gu-sest). Related vocabulary includes päev (day), valgus (light) and compounds or derivatives built on the same roots.
