IPA: /ˈfɒɡboʊ/
KK: /ˈfɔgˌboʊ/
A faint, arc-shaped light that can appear in fog, often opposite the sun, resembling a rainbow.
The fogbow created a beautiful arc of light in the misty morning.
Fogbow → The word is formed from "fog" (from Old English *fogga*, meaning a mass of condensed water vapor) and "bow" (from Old English *boga*, meaning a curve or arch). A fogbow is thus an arc or bow formed by fog, similar to a rainbow but created by the scattering of light in fog rather than rain.
Imagine a 'mass of condensed water vapor' ('fog') creating a 'curved arch' ('bow') in the sky — that's how a fogbow appears.
