Nondefense → It is formed from "non-" (meaning not) and "defense" (from Latin "defensio", meaning protection or defense). The word "nondefense" means the absence of defense or protection.
Think of 'non-' meaning 'not' and 'defense' meaning 'protection' — so nondefense refers to a lack of protection.
