An integrity synonym can mean two quite different things, so start by asking which kind you need. For people, the best swaps are honesty, honor, principle and decency. For buildings, data and systems, soundness and wholeness are the words.
Integrity is a favorite on company value lists and in reference letters, which is exactly why it can sound empty. A more specific noun, or a short example of honest behavior, often lands better.

Honesty is about telling the truth. Integrity also covers doing right when nobody checks.
Integrity synonym options for people
When integrity describes character, it bundles several ideas: telling the truth, keeping promises and holding to a moral code. Each synonym picks out one of those threads.
| Word | Focus | In a sentence |
|---|---|---|
| honesty | truthfulness | Her honesty about the error won respect. |
| honor | keeping your word | He was a man of honor who paid every debt. |
| principle | following firm rules | She refused the gift on principle. |
| decency | basic goodness toward others | Common decency means you return the call. |
| fairness | treating people equally | The referee was known for fairness. |
| probity | strict honesty with money or office | Public officials must show probity. |
Plain to advanced vocabulary
The strip of five words moves from everyday to scholarly. Honesty is understood by everyone. Decency is warm and human. Honor carries a slightly traditional feel. Uprightness sounds stiff and slightly dated. Probity belongs in governance reports and legal writing, where it describes leaders who handle money and power cleanly.
A school essay will rarely need probity. A paper on public ethics might use it once to great effect.
Structural, data and system integrity
Engineers talk about the integrity of a bridge, and programmers talk about data integrity. Here the word means being whole, undamaged and reliable.
- The integrity of the wall was in doubt becomes the soundness of the wall was in doubt.
- Check the integrity of the file becomes check that the file is complete and uncorrupted.
- Territorial integrity becomes territorial unity in some contexts, though the original phrase is standard in politics.
Honesty would make no sense in these lines, so keep the two senses apart.
Another word for integrity at work
Many value statements read "we act with integrity". Try something that says what you actually do: we are transparent about pricing, we keep our promises, we admit mistakes quickly. In a reference letter, trustworthiness and reliability tell an employer exactly what they gain.
A recommendation line: "Sam has great integrity." A stronger version: "Sam is scrupulously honest; when a client was overcharged, he flagged it before anyone noticed." The adjective plus a short story proves the point. Browse the work vocabulary hub for related terms.
Close cousins that are not the same
Trust is what others feel toward you because of your integrity; it is not the quality itself. Respect is admiration, which integrity may earn. Loyalty means staying on someone's side, and a loyal person can still lie for a friend. Pride is about self-worth, not ethics.
Antonyms for both senses
For character, the opposites are dishonesty, deceit, corruption and hypocrisy. Hypocrisy is especially useful: it means saying one thing and doing another, which is the exact failure integrity guards against. For structures, use weakness, fragility or instability.
- The scandal exposed years of corruption.
- Cracks revealed the fragility of the old pier.
