IPA: /ˈhɛlm.ləs/
KK: /ˈhɛlm.ləs/
Not having a steering device, especially on a ship.
The ship was helmless, drifting aimlessly in the open sea.
Helmless → It is formed from "helm" (from Old English "helm", meaning a protective covering or helmet) and "-less" (meaning without). The word "helmless" means without a helmet or protection, often used metaphorically to describe a lack of guidance or leadership.
Think of being 'without' ('-less') a 'helmet' ('helm') — that's why helmless means lacking protection or guidance.
