kütmisel

Kütmisel is an Estonian adverbial noun formed from the verb kütma (to burn, to fuel) via the verbal noun kütmine and the suffix -misel. It expresses that an action or state occurs in the act of burning or during combustion, roughly equivalent to the English phrases “in the act of burning” or “during combustion.” As a gerundial form, it designates a circumstance or time frame rather than a specific event with its own subject.

In use, kütmisel functions as an adverbial noun that can indicate simultaneity or condition without a finite verb. It is more common in technical, safety, or formal descriptions of processes involving burning or fuel use. In everyday language, speakers often replace it with phrases like kütmise ajal (“during combustion”) or use participial constructions such as kütmisel olev to describe something that is currently in the burning or fueling state.

Examples of usage include technical and descriptive contexts. For instance, Kütmisel olev mootor tarbib rohkem kütust. (The engine in operation consumes more fuel.) In an environmental or safety context: Jäätmekatla kütmisel tekivad heitmed. (Emissions are produced during waste incineration.) These usages illustrate how kütmisel condenses the idea of a process that is actively burning or being fueled.

Related terms include kütmine (burning, fuel use) and kütmise ajal (during combustion). While kütmisel provides a compact way to refer to the ongoing burning process, the more explicit phrases are often clearer in everyday language.
