Märkamatute
Märkamatute is a term used in Estonian to describe something that is imperceptible or unnoticed. It can refer to physical phenomena, abstract concepts, or even actions that occur without attracting attention. The root of the word, "märkama," means to notice or perceive, and the suffix "-tute" indicates a lack of or absence of something. Therefore, "märkamatute" literally translates to "unnoticed" or "unperceivable."
In a scientific context, "märkamatute" can describe stimuli that are below the threshold of human perception,
