Etymology
The term is a modern compound built from deeply rooted English elements. 'Self' originates from Proto-Germanic selbaz, carrying the core sense of one's own identity. 'Fulfill' combines the concepts of completeness ('full') and execution ('fill'), tracing back to Proto-Germanic fullijaną. The adjective-forming '-ing' suffix is a native English participial ending. The concept's logic is elegantly literal: a 'self-fulfilling' prophecy is one that 'fulfills itself' because the belief in its prediction directly influences behavior to bring about the predicted outcome, creating a loop where cause and effect merge.
