peegeldavaid

Peegeldavaid is an Estonian word form derived from the adjective peegeldav, which means reflective or refractive. The base meaning describes surfaces or phenomena that can reflect light, sound, or other waves. The form peegeldavaid appears when the modified noun is plural and in the partitive case, for example peegeldavaid pindu (reflective surfaces) or peegeldavaid omadusi (reflective properties). In linguistic terms, peegeldav is formed from the verb peegeldama (to reflect) with the suffix -dav, creating a present active participle; peegeldavaid is one of its inflected forms used in sentences.

Etymology and meaning: peegeldav combines peegel (mirror) with the verb-forming element -dav, signaling a mirroring or reflecting quality. The term is commonly understood in Estonian to describe reflectivity in physical, optical, or metaphorical contexts.

Usage: The form is typical in technical and scientific writing about optics, materials science, or design, where the reflectivity of surfaces is discussed. Examples include peegeldavaid pindu (reflective surfaces) and peegeldavaid omadusi omav materjal (a material with reflective properties). In everyday language, the simpler adjective peegeldav is more common, while peegeldavaid is used when a plural, partitive construction is required.
