Here's a breakdown:
* Promise: A declaration assuring someone that you will do something or that something will happen.
* Deliver: To bring something to someone, often as promised.
Therefore, "deliver a promise" signifies that you have successfully carried out the action or provided the outcome you pledged.
Here are some examples:
* "He promised to deliver the goods by Friday, and he did." (He fulfilled his commitment.)
* "The company delivered on its promise to improve customer service." (They made a change that they said they would.)
* "She promised to stay in touch, and she's been delivering on that promise." (She's keeping her word.)
In essence, delivering a promise means being trustworthy and reliable. It shows that you can be counted on to follow through on your word.
