Linguistic Origin & Historical Etymology

Derived from the Greek prefix 'auto-' meaning 'self' combined with 'annihilation', which stems from the Latin 'annihilare' (to bring to nothing, from 'nihil' meaning 'nothing'). First appearing in scientific and philosophical literature in the late 19th century, the term evolved to describe processes of self-destruction, particularly in physics and theoretical contexts.
