IPA: /ˈhɛl.wɚd/
KK: /hɛlˌwɔrd/
In the direction of hell; moving or pointing toward a place considered to be hell.
The lost souls wandered hellward, seeking redemption.
Hellward is formed from "hell" (from Old English *hell*, meaning the underworld or a place of torment) and "-ward" (meaning in the direction of or towards). The word "hellward" means moving or directed towards hell.
Imagine someone moving 'towards' ('-ward') a place of torment ('hell') — that's why hellward means heading in the direction of hell.
