Tõestamisel

Tõestamisel is an Estonian noun form derived from the verb tõestama, meaning to prove or verify. The word denotes the process or activity of proving something and is often translated as “in proving,” “during the proving,” or “in the course of establishing.” It describes a stage or methodological aspect of establishing truth rather than the final conclusion itself.

Linguistically, -misel is a non-finite suffix that forms a noun indicating an action or process. Tõestamisel can function as an adverbial or modifier in a sentence, signaling that the statement refers to the act of proving. This form is common in legal, scientific, and philosophical discourse, where emphasis is placed on how evidence is gathered, evaluated, or presented.

In usage, tõestamisel appears in contexts such as legal proceedings, research, and arguments where the method and process of establishing a claim are important. Examples include phrases like tõendamisel olevad materjalid (materials in the process of proving) or tõestamisel olevad väited (claims being proven). The term helps distinguish the act of proving from the concrete evidence (tõend) or the end result of a proof (tõestus).

Relation to related terms: tõestamine refers to the act or practice of proving in general, while tõend refers to evidence used to support a claim. Tõestamisel differs by focusing on the ongoing process rather than the finished proof or the evidence itself.
