Etymology

The word traces back to Late Latin vulnerabilis, combining vulnus (wound) with -abilis (ability). It originally described susceptibility to physical injury, later expanding to emotional and metaphorical fragility. The root vulnus also appears in "vulnerary" (wound-healing) and reflects Indo-European wele- (to strike).
