Kuumusest

Kuumusest is an Estonian grammatical form, the elative singular of the noun kuumus, which means heat or high temperature. It expresses origin, source, or cause and is used to indicate something arising from or caused by heat, literally “from heat.”

In usage, kuumusest appears in scientific and everyday language to discuss effects and phenomena related to high temperatures. For example, it can describe health effects such as dehydration caused by heat, or environmental conditions that originate in heat. The phrase kuumuse tõttu or kuumusest tingitud is commonly used to link a result to heat, with kuumusest functioning as the source noun in such constructions.

Etymologically, kuumusest is formed by the stem kuumus combined with the elative suffix -est, signaling movement away from or origin in heat. It is one of several Estonian case forms used to express relationships of source, direction, or causation in relation to the noun kuumus.

As a grammatical form, kuumusest is not a standalone concept but a functional tool within Estonian syntax. It can be found in meteorological descriptions, medical discussions of heat-related conditions, and in general prose when the author wishes to attribute an effect to heat.
