vajalikkusel

Vajalikkusel is an Estonian grammatical term that denotes the adessive form of the noun vajalikkus, meaning necessity or essentiality. It signals a circumstance in which an action, obligation, or condition arises from necessity rather than from voluntary choice. In formal writing, vajalikkusel is used to frame provisions, obligations, or policies that apply specifically in times of need or scarcity.

The term vajalikkus is formed from vajalik, meaning necessary, with a noun suffix to create a concept of necessity. The adessive case of vajalikkus is vajalikkusel, rendered to express “in a state of necessity” or “under necessity.” The form is common in regulatory, legal, and policy prose where it is important to distinguish actions taken under necessity from those taken by choice.

Usage of vajalikkusel is specialized and more frequent in official, legal, or planning contexts than in everyday speech. Typical phrases include “vajalikkusel tekkivad kohustused” (obligations arising in times of necessity) and “vajalikkusel kehtestatud meetmed” (measures enacted under necessity). It should be distinguished from vajalikkus (the state of necessity) and vajadus (a need).
