Integrity is the quality of being honest and having strong moral principles. It means doing the right thing even when no one is watching.
For example, if you find a wallet on the ground and return it to its owner without taking any money from it, you are showing integrity. Integrity also means being truthful and keeping your promises.
Very Simple Definition:
Integrity is about being honest and doing the right thing. It means not lying or taking things that don’t belong to you. For example, if you see money that someone dropped and you return it to them instead of taking it, that is integrity.
