rakendamisel

Rakendamisel is an Estonian grammatical form derived from the verb rakendada, meaning to implement or to apply. It denotes the state or period during which something is being implemented and is used to express circumstantial meaning—specifically the conditions, timing, or manner under which an action occurs. In usage, rakendamisel typically accompanies a noun in the genitive to specify what is being implemented, for example projekti rakendamisel ("during the implementation of the project") or programmi rakendamisel ("during the implementation of the program"). It is common in formal and technical writing, such as policy documents, project plans, laws, and software deployment guidelines.

In sentences, rakendamisel serves as an adverbial participle or circumstance marker, answering questions about when or under what conditions an action takes place. It can be paraphrased as "during the implementation," "in the course of applying," or replaced with phrases such as rakendamise ajal or rakendamise käigus in Estonian.

Etymology and related forms: The base noun rakendamine means "implementation." The form rakendamisel is the noun in a particular case or participial function used to express time or condition. Related terms include rakendamine (the act of implementing) and rakendamise käik (the course of implementation). In some contexts, the English loanword implementatsioon may appear, though rakendamine is more idiomatic in Estonian.
