Producing no effect; having no impact, consequence, or result; powerless or futile.
From 'effect' plus the suffix '-less' (without). The construction literally means 'without effect' or 'lacking effects.'
The '-less' suffix creates a philosophical weight here—something 'effectless' isn't just ineffective temporarily, it's fundamentally incapable of making any difference at all. It suggests a cosmic futility rather than mere failure.
