lennukist

Lennukist is the elative singular form of the Estonian noun lennuk, meaning airplane or aircraft. It functions to express origin or source, roughly translating to “from the airplane” in English. The form is produced by adding the elative suffix -st to the stem lennuk.

In Estonian grammar, the elative case indicates movement away from a place or source of something and is used with verbs of origin, emanation, or departure, as well as after certain prepositions. Lennukist thus marks origin specifically from an airplane, rather than from a location on or inside the plane.

Usage examples include: Lennukist kostis vaikne müra. (A faint noise came from the airplane.) Ta vaatas välja lennukist. (He looked out from the airplane.) These examples illustrate how lennukist conveys the source of an action or sensation.

Lennukist is one of several inflected forms of lennuk. Other cases include lennuki (genitive: of the airplane), lennukis (inessive: in/on the airplane), and lennukile (allative: onto/to the airplane). The elative form is distinct in both meaning and usage, and is typically used when the sentence centers on origin or source from the aircraft.
