causeless
Lacking any cause
Without cause, reason, or justification.
A causeless fear has no identifiable source; a causeless act lacks apparent motivation.
The word appears most often in philosophical or literary contexts: causeless suffering, causeless hatred.
Something causeless simply exists or occurs without explanation or trigger.
