Hehkuun

Hehkuun is a Finnish term that translates to "to glow" or "to be incandescent." It is primarily used in a literal sense to describe the emission of light by a substance due to high temperature. For instance, metal heated to a sufficient temperature will hehkuun, emitting a visible orange or red light. This phenomenon is a fundamental concept in physics and material science, relating to black-body radiation.

Beyond its literal meaning, hehkuun can also be used metaphorically in Finnish to describe a state of intense emotion or feeling. For example, someone experiencing great joy or passion might be described as hehkuun. This figurative usage conveys a sense of inner warmth, radiance, and powerful emotion that emanates from a person. It suggests a state of being deeply moved or inspired, with their feelings visibly or palpably present. The term captures both physical luminescence and the outward expression of strong internal states.
