Satisfaction is the pleasant feeling you get when your needs, desires, or expectations are met. It can also mean fulfilling a duty or settling a claim or debt.
From Latin *satisfactio*, from *satis* 'enough' and *facere* 'to make or do', literally 'making enough'. It originally had strong legal and religious senses of fully meeting a requirement.
Satisfaction literally means 'made enough'—as if your mind or situation finally reaches a level that feels complete. That’s why it appears in law, religion, and customer service: all are trying to reach 'enough-ness'. The word quietly suggests that contentment is about a threshold, not perfection.
