The story behind it
Word for word the saying reads “prudence power is”, with the verb at the end, which is normal Latin word order. It means that prudence, meaning sound practical judgement, is itself a form of power.
The wording is modelled on scientia potentia est, “knowledge is power”, a phrase tied to Francis Bacon and the early modern period. This version swaps knowledge for prudence and has no single classical author.
Prudentia was a prized virtue in Roman thought: the ability to see what lies ahead and choose well. Today the line is used as a modern motto on cards, desks and walls, and by people who value careful judgement over brute force.

Common mistakes
- It is not an ancient Roman proverb. It is a modern Latin saying built on the pattern of scientia potentia est.
- Prudentia is not “prudishness”. It means practical wisdom and foresight, not being overly cautious or strait-laced.
- Do not swap the nouns for other genders or cases without care: both words are feminine nominative singular, and the verb est stays the same.
- Reversing the order to Potentia prudentia est would change the emphasis and read as “power is prudence”.
