Here's why:
* Consistent means unchanging, regular, or uniform.
* Agreeing means to be in harmony or accord.
If someone is consistent in their beliefs or actions, they are always agreeing with themselves. This implies a lack of conflict or contradiction in their thoughts and behavior.
For example:
* "The witness's testimony was consistent with the evidence presented." (The witness's testimony agreed with the evidence).
However, "agreeing" can also refer to a mutual agreement between two or more parties. In this case, consistent is not a perfect synonym, but it can be used to describe a situation where individuals are agreeing with each other over time.
For example:
* "The negotiators were consistent in their efforts to reach an agreement." (The negotiators continuously agreed to work towards a common goal).
It's important to consider the context of the situation to determine if "consistent" and "agreeing" are truly synonymous.
