kiirgab

Kiirgab is an Estonian verb meaning to radiate or emit light, heat, or energy. It can also be used metaphorically to describe warmth, vitality, or charisma emanating from a person or thing. The infinitive is kiirgama; the present tense, third-person singular, is kiirgab, as in “Päike kiirgab.” Related forms include kiirgav (radiant, radiating) and kiirgus (radiation, glow). The root kiirg- belongs to a semantic field of light and brightness and appears in several Estonian words dealing with light.

In usage, kiirgab is common in both scientific and descriptive language. It can describe actual emission of light or heat, as in scientific writing, or be used poetically to convey brightness or intensity. For example: “Päike kiirgab eredalt.” or “Tema naeratus kiirgab enesekindlust,” where a smile radiates confidence.

Etymology and related terms: kiirgus is the noun for radiation or glow, and kiirgav functions as a present participle meaning radiating or glowing. The word is part of everyday Estonian vocabulary for describing visible brightness as well as figurative brilliance.

Notes: Kiirgab is strictly a verb form; it is not a standalone noun. Its figurative use relies on the common association between light and positive traits such as warmth or vitality.
