A more thorough explanation:

Definition: Constitutional is an adjective that describes something that is related to a constitution or is proper and valid under a constitution.

Examples:

• Constitutional rights: These are the rights that are protected by the constitution of a country. For example, in the United States, the First Amendment guarantees the constitutional right to freedom of speech.
• Constitutional actions: These are actions that are allowed and in line with the constitution of a country. For example, a president's decision to veto a bill is a constitutional action because it is within their power according to the constitution.

The examples illustrate how something can be considered constitutional if it is in accordance with the laws and principles set forth in a constitution. Constitutional rights are protected by the constitution and cannot be taken away without due process. Constitutional actions are those that are allowed and within the scope of power granted by the constitution.
