Algatusel

Algatusel is an Estonian adessive form of the noun algatus, meaning “on the initiative of” or “at the initiative of.” It is used to attribute the origin of an action or project to a person or organization.

In grammar, algatusel is created by adding the adessive suffix -l to algatus. It is commonly used in formal and public-language contexts, such as official statements, press releases, and event descriptions. When used to identify the initiator, the acting entity appears in the genitive after algatusel, for example: Algatusel Noorteühenduse korraldati konverents (“A conference was organized on the initiative of the Youth Association”).

Usage and nuance: algatusel emphasizes the source of the action—the initiator rather than the responsibility or legal basis. It is distinct from phrases that describe the basis or rule for an action, such as alusel or järgi. The expression is versatile and can refer to initiatives by nonprofit organizations, government bodies, institutions, or informal groups.
