Jäähtymättömämmän

Jäähtymättömämmän is the genitive singular form of the Finnish adjective "jäähtymätön," which means "non-cooling" or "uncooled." In Finnish grammar, the genitive case is often used to express possession, origin, or to modify another noun. Therefore, "jäähtymättömämmän" would typically be used in a context where something is described as being "of something that is non-cooling" or in relation to a concept of being "more non-cooling."

The root word "jäähtymätön" itself is derived from the verb "jäähtyä," meaning "to cool down," with the suffix "-mätön" indicating the absence of the action or state. Thus, "jäähtymätön" literally means "not having cooled down" or "remaining uncooled."

The comparative form "jäähtymättömämmän" implies a degree of this state. It suggests a comparison, meaning "of a more non-cooling thing" or "than something that is more uncooled." For instance, one might say that a certain material is "jäähtymättömämmän" than another, implying it retains heat to a greater extent. The specific usage and meaning would heavily depend on the surrounding sentence and context in which this word appears. It is not a commonly encountered standalone term but rather a grammatical variation used to express nuanced comparisons related to the state of being uncooled.
