What is the meaning of word caveat?

A caveat is a warning or proviso that limits or qualifies a statement or claim. It can also be a formal legal notice that stops a particular action from taking place.

Here are some examples:

* "He agreed to help, with the caveat that he would only work on weekends." This means he agreed to help, but only under the specific condition that he would only work on weekends.

* "The new policy comes with the caveat that it may need to be revised in the future." This means the policy is subject to change.

* "The lawyer filed a caveat to prevent the sale of the property." This means the lawyer took legal action to stop the sale of the property.

In essence, a caveat acts as a "but" or "however", adding a note of caution or reservation to a statement.
