Complete destruction or obliteration; the act of reducing something to nothing. Can refer to physical destruction or complete defeat.
From Latin 'annihilatio' meaning 'reduction to nothing,' from 'ad-' (to) + 'nihil' (nothing). The concept entered English in the 14th century through theological discussions about God's power to destroy.
Remember 'NIHIL' means 'nothing' in Latin (like 'nihilism') - so annihilation literally means 'making into nothing.' Think of it as the ultimate deletion - not just destroying, but making something cease to exist entirely!
