self-annihilation

The term is a modern philosophical and psychological compound, built from deeply rooted components. "Self" originates from the Proto-Germanic selbaz, carrying the core sense of one's own identity or person. "Annihilation" traces back to the Latin 'nihil', meaning "nothing," itself potentially from a Proto-Indo-European root meaning "to disappear." The literal, ancient sense of "making oneself into nothing" provides a powerful metaphor for the modern abstract concepts. These range from the physical or psychological destruction of the ego to the theological concept of the soul's merging with the divine, where the individual self is extinguished.

Structure: self (own) + annihilation (complete destruction) self: Old English, meaning "one's own person." It functions as a prefix denoting reflexivity or action directed upon oneself. annihilation: From Latin, composed of 'ad-' (to) + 'nihil' (nothing) + the noun-forming suffix '-ation'. It functions as the core noun meaning "the act of reducing to nothing."
