läpäisemätömäksi

Lépaisseur is a Finnish word that translates to "impermeable" or "impenetrable" in English. It is an adjective used to describe something that cannot be penetrated, passed through, or permeated. This can refer to physical substances, abstract concepts, or even situations.

In a physical context, läpäisemätön can describe materials that block the passage of liquids, gases, or other substances. For example, a waterproof fabric is läpäisemätön to water. Similarly, a sealed container is läpäisemätön to air. This property is crucial in many applications, such as construction, packaging, and protective gear.

Beyond the physical realm, läpäisemätön can be used metaphorically. It can describe a belief or opinion that is resistant to change or persuasion. Someone might be described as having läpäisemätön resistance to new ideas if they are unwilling to consider alternative viewpoints. In a broader sense, a situation could be described as läpäisemätön if it presents an insurmountable obstacle or a deadlock.

The etymology of the word provides further insight. It is formed from the verb "läpäistä" (to penetrate, to pass through) and the negative suffix "-mätön" (un-, -less). Thus, läpäisemätön literally means "un-penetratable" or "that which cannot be passed through." The concept it conveys is one of absolute resistance or impermeability.
