Peegelduv

Peegelduv is an Estonian adjective meaning "mirror-like" or "reflective." It describes surfaces that reflect light or sound with clarity, as well as phenomena or ideas that involve reflection. The word is formed from peegel ("mirror") and the suffix -duv, which marks a characteristic or quality. It is closely related to peegeldama ("to reflect") and to peegel, the word for mirror.

In optics, peegelduv pind refers to surfaces capable of specular reflection, such as polished metal, glass, or a calm body of water. In acoustics, peegelduv surfaces reflect sound waves rather than absorbing them. In everyday language and literature, peegelduv is used metaphorically to denote introspection or a contemplative mood, for example peegelduv mõtteviis (reflective mindset) or peegelduv kujund (mirror-like motif).

Peegelduv can also describe contexts where symmetry or mirroring is important, such as in design or imaging, where a peegelduv rendering shows a mirror image of an object. The term is commonly used across science, art, and cultural discourse to convey both literal reflection and figurative contemplation. Related terms include peegel (mirror) and peegeldus (reflection). The usage remains neutral and descriptive, suitable for encyclopedic contexts.
