tühjendamisel

Tühjendamisel is the Estonian form used to express “during emptying” or “in the course of emptying.” It is a grammatical construction derived from the noun tühjendamine, which means the process of emptying or draining, and it uses the adessive suffix to indicate the time or context in which another action occurs.

Formation and function: The base concept tühjendamine denotes the action of emptying. By adding the appropriate adessive form, the phrase tühjendamisel communicates that something happens while or during the emptying takes place. This construction is common in technical, procedural, and scientific writing where precise timing is important.

Usage and contexts: Tühjendamisel is typically found in manuals, safety protocols, engineering reports, and medical or laboratory procedures. It marks a concurrent action or a required condition that applies specifically to the period of emptying. In everyday language, speakers often substitute with phrases like tühjendamise ajal or tühjendamise käigus, which have the same meaning but a more colloquial tone.

Examples:

- Tanki tühjendamisel tuleb järgida ohutusnõudeid. (During tank emptying, safety requirements must be followed.)

- Masina tühjendamisel kontrolliti pesemislahuse jäänuseid. (During the machine’s emptying, residues of the cleaning solution were checked.)

See form is not a separate lexical entry but a grammatical variant of the noun tühjendamine, used to specify temporal context in Estonian prose. It is especially prevalent in written and technical style, where concise timing information matters.
