A more thorough explanation:

Term: pro majori cautela
Definition: When someone does something for greater caution or security, they use the Latin phrase "pro majori cautela". This phrase is often used when someone wants to take extra precautions or add a clause to a document to make sure everything is safe and secure.
Example: Before signing the contract, the lawyer added a pro majori cautela clause to make sure their client was protected in case of any unforeseen circumstances. This means that the lawyer added an extra clause to the contract to make sure their client was safe and secure.
