esialgsest

Esialgsest is the elative singular form of the Estonian adjective esialgne, meaning initial or preliminary. In linguistic and technical usage, esialgsest is used to indicate that something comes from or originates in the initial stage or phase of a process. It is typically found with nouns in the elative case, and appears most often in formal or academic texts.

In terms of grammar, esialgsest is an inflected form that agrees with a noun in the elative case. When combined with a noun in elative, the phrase esialgsest [noun in elative] translates roughly to “from the initial …” or “out of the initial ….” This construction is common in descriptions of stages, phases, or sequences within reports, studies, and technical documents.

Usage examples are most frequent in research contexts. For instance, esialgsest etapist pärinevad andmed means “data originating from the initial stage.” Another example could refer to recommendations or conclusions drawn from early work, phrased as esialgsest analüüsist tulenevad järeldused (drawn from the initial analysis). The term thus helps distinguish early-phase material from results obtained later in a project.
