How do you do use the word “compromise “ on the meaning of agreement or understanding??

Question

Answer

In addition to being a verb like in Ravisha's examples, "compromise" can also be a noun:

They reached a compromise.

Answer

an agreement in an argument in which the people involved reduce their demands or change their opinion in order to agree

If you compromise in an argument, it means that you (and the other person) will have to reduce what you want from each other to reach a solution that you both can agree on.

For example:
Well, you want $400, and I say $300, so let's compromise on $350.
