Here are some examples:
* "The teacher's explanation led to a deeper understanding of the subject."
* "There's a mutual understanding between the two friends."
* "He has a good understanding of human nature."
In these sentences, "understanding" refers to a concept, a state of knowing something, or an agreement.
It's important to note that "understanding" can also be a verb:
* "I am trying to understand the instructions."
In this case, "understanding" describes an action.
