IPA: /ˈʌndərˌlɪt/
KK: /ˈʌndərˌlɪt/
Describing something that is lit from below or not well lit, often creating a shadowy or dim effect.
The stage was underlit, making it hard to see the performers clearly.
Underlit → It is formed from "under-" (meaning beneath or below) and "lit" (from Old English "lyhtan", meaning to illuminate or light). The word "underlit" describes something that is illuminated from below.
Think of something being lit from 'beneath' ('under-') — that's why underlit means it is illuminated from below.
