IPA: //ˈsʌn.dɔɡ//
KK: /ˈsʌnˌdɔg/
A bright spot that appears on either side of the sun, often creating a halo effect in the sky.
We saw a beautiful sundog while hiking on the mountain.
Sundog is formed from "sun" (from Old English "sunne", meaning the star that gives light) and "dog" (from Old English "docga", meaning a dog or a powerful breed of dog). The term "sundog" refers to a bright spot that appears on either side of the sun, resembling a dog following the sun.
Think of the 'sun' as the bright star in the sky and 'dog' as a loyal companion. A sundog is like a companion to the sun, appearing beside it in the sky.
