security
Freedom from danger
Security is the condition of being safe from danger, fear, or anxiety: Their financial situation offers them security.
This core meaning, an uncountable noun, inspires all others.
Security often refers to the active protection of people or places against threats: tighten security, improve security.
When security teams up with another noun, the resulting compound usually describes the safety concerns of a particular domain: computer security, food security.
The plural securities usually refers to investments.
