IPA: /ˈfɔːrsləs/
KK: /ˈfɔrsləs/
Having little or no strength or power; weak.
The forceless argument failed to convince anyone in the debate.
Forceless → It is formed from "force" (from Old French *forse*, meaning strength or power) and "-less" (meaning without). The word "forceless" means lacking strength or power.
Think of being 'without' ('-less') 'strength' ('force') — that's why forceless means lacking strength.
